Power Corp. makes 2 products: blades for table saws and blades for handsaws. Each product passes through the sharpening machine area, which is the chief constraint during production. Handsaw blades take 15 minutes on the sharpening machine and have a contribution margin per blade of $15. Table saw blades take 20 minutes on the sharpening machine and have a contribution margin per blade of $35. If it is assumed that Power Corp. has 5,000 hours available on the sharpening machine to service a minimum demand for each product of 4,000 units, how many of each product should be made?
Hatch Manufacturing produces multiple machine parts. The theoretical cycle time for one of its products is 65 minutes per unit. The budgeted conversion costs for the manufacturing cell dedicated to the product are 12,960,000 per year. The total labor minutes available are 1,440,000. During the year, the cell was able to produce 0.6 units of the product per hour. Suppose also that production incentives exist to minimize unit product costs. Required: 1. Compute the theoretical conversion cost per unit. 2. Compute the applied conversion cost per minute (the amount of conversion cost actually assigned to the product). 3. Discuss how this approach to assigning conversion cost can improve delivery time performance. Explain how conversion cost acts as a performance driver for on-time deliveries.
Gent Designs requires three units of part A for every unit of Al that it produces. Currently, part A is made by Gent, with these per-unit costs in a month when 4.000 units were produced: Variable manufacturing overhead is applied at $1.00 per unit. The other $0.30 of overhead consists of allocated fixed costs. Gent will need 6,000 units of part A for the next years production. Cory Corporation has offered to supply 6,000 units of part A at a price of $7.00 per unit. It Gent accepts the offer, all of the variable costs and $1,200 of the fixed costs will be avoided. Should Gent Designs accept the offer from Cory Corporation?
Dimitri Designs has capacity to produce 30,000 desk chairs per year and is currently selling all 30,000 for $240 each. Country Enterprises has approached Dimitri to buy 800 chairs for $210 each. Dimitris normal variable cost is $165 per chair, including $50 per unit in direct labor per chair. Dimitri can produce the special order on an overtime shift, which means that direct labor would be paid overtime at 150% of the normal pay rate. The annual fixed costs will be unaffected by the special order and the contract will not disrupt any of Dimitris other operations. What will be the impact on profits of accepting the order?
Aril Industries is a multiproduct company that currently manufactures 30,000 units of Part 730 each month for use in production. The facilities now being used to produce Part 730 have fixed monthly overhead costs of 150,000 and a theoretical capacity to produce 60,000 units per month. If Aril were to buy Part 730 from an outside supplier, the facilities would be idle, and 40% of fixed costs would continue to be incurred. There are no alternative uses for the facilities. The variable production costs of Part 730 are 11 per unit. Fixed overhead is allocated based on planned production levels. If Aril Industries continues to use 30,000 units of Part 730 each month, it would realize a net benefit by purchasing Part 730 from an outside supplier only if the suppliers unit price is less than: a. 12.00. b. 12.50. c. 13.00. d. 14.00.
Remarkable Enterprises requires four units of part A for every unit of Al that it produces. Currently, part A is made by Remarkable, with these per-unit costs in a month when 4,000 units were produced: Variable manufacturing overhead is applied at $1.60 per unit. The other $0.50 of overhead consists of allocated fixed costs. Remarkable will need 8,000 units of part A for the next years production. Altoona Corporation has offered to supply 8,000 units of part A at a price of $8.00 per unit. If Remarkable accepts the offer, all of the variable costs and $2,000 of the fixed costs will be avoided. Should Remarkable accept the offer from Altoona Corporation?
At Stardust Gems, a faux gem and jewelry company, the setting department is a bottleneck. The company is considering hiring an extra worker, whose salary will be $67,000 per year, to ease the problem. Using the extra worker, the company will be able to produce and sell 9,000 more units per year. The selling price per unit is $20. The cost per unit currently is $15.85 as shown: What is the annual financial impact of hiring the extra worker for the bottleneck process?
Computador has a manufacturing plant in Des Moines that has the theoretical capability to produce 243,000 laptops per quarter but currently produces 91,125 units. The conversion cost per quarter is 7,290,000. There are 60,750 production hours available within the plant per quarter. In addition to the processing minutes per unit used, the production of the laptops uses 10 minutes of move time, 20 minutes of wait time, and 5 minutes of rework time. (All work is done by cell workers.) Required: 1. Compute the theoretical and actual velocities (per hour) and the theoretical and actual cycle times (minutes per unit produced). 2. Compute the ideal and actual amounts of conversion cost assigned per laptop. 3. Calculate MCE. How does MCE relate to the conversion cost per laptop?
Lander Parts, Inc., produces various automobile parts. In one plant, Lander has a manufacturing cell with the theoretical capability to produce 450,000 fuel pumps per quarter. The conversion cost per quarter is 9,000,000. There are 150,000 production hours available within the cell per quarter. Required: 1. Compute the theoretical velocity (per hour) and the theoretical cycle time (minutes per unit produced). 2. Compute the ideal amount of conversion cost that will be assigned per subassembly. 3. Suppose the actual time required to produce a fuel pump is 40 minutes. Compute the amount of conversion cost actually assigned to each unit produced. What happens to product cost if the time to produce a unit is decreased to 25 minutes? How can a firm encourage managers to reduce cycle time? Finally, discuss how this approach to assigning conversion cost can improve delivery time. 4. Assuming the actual time to produce one fuel pump is 40 minutes, calculate MCE. How much non-value-added time is being used? How much is it costing per unit? 5. Cycle time, velocity, MCE, conversion cost per unit (theoretical conversion rate actual conversion time), and non-value-added costs are all measures of performance for the cell process. Discuss the incentives provided by these measures.
Shelby Industries has a capacity to produce 45.000 oak shelves per year and is currently selling 40,000 shelves for $32 each. Martin Hardwoods has approached Shelby about buying 1,200 shelves for a new project and is willing to pay $26 each. The shelves can be packaged in bulk; this saves Shelby $1.50 per shelf compared to the normal packaging cost. Shelves have a unit variable cost of $27 with fixed costs of $350,000. Because the shelves dont require packaging, the unit variable costs for the special order will drop from $27 per shelf to $25.50 per shelf. Shelby has enough idle capacity to accept the contract. What is the minimum price per shelf that Shelby should accept for this special order?
Use the information provided to create a standard cost card for production of one glove box switch. To make one switch it takes 16 feet of plastic-coated copper wire and 0.5 pounds of plastic material. The plastic material can usually be purchased for $20.00 per pound, and the wire costs $2.50 per foot. The labor necessary to assemble a switch consists of two types. The first type of labor is assembly, which takes 3.5 hours. These workers are paid $27.00 per hour. The second type of labor is finishing, which takes 2 hours. These workers are paid $29.00 per hour. Overhead is applied using labor hours. The variable overhead rate is $14.90 per labor hour. The fixed overhead rate is $15.60 per hour.
Jansen Crafters has the capacity to produce 50,000 oak shelves per year and is currently selling 44,000 shelves for $32 each. Cutrate Furniture approached Jansen about buying 1,200 shelves for bookcases it is building and is willing to pay $26 for each shelf. No packaging will be required for the bulk order. Jansen usually packages shelves for Home Depot at a price of $1.50 per shell. The $1.50 per-shelf cost is included in the unit variable cost of $27, with annual fixed costs of $320.000. However, the $130 packaging cost will not apply in this case. The fixed costs will be unaffected by the special order and the company has the capacity to accept the order. Based on this information, what would be the profit if Jansen accepts the special order? A. Profits will decrease by $1,200. B. Profits will increase by $31,200. C. Profits will increase by $600. D. Profits will increase by $7,200.
