Because of its labor contract, a company must hire enough labor for 100 units ofproduction per week on one shift or 200 units per week on two shifts. It cannot hire,lay off, or assign overtime. During the fourth week, workers will be available fromanother department to work part or all of an extra shift (up to 100 units). There is aplanned shutdown for maintenance in the second week, which will cut production tohalf. Develop a production plan. The opening inventory is 200 units, and the desiredending inventory is 300 units
Box Electric makes electronic components and has estimated the following for a new design of one of its products.
Fixed cost = $24,975
Material cost per unit = $0.17
Labor cost per unit = $0.12
Revenue per unit = $0.66
Note that fixed cost is incurred regardless of the amount produced. Per-unit material and labor cost together make up the variable cost per unit. Assuming that Box Electric sells all that it produces, profit is calculated by subtracting the fixed cost and total variable cost from total revenue.
Construct an appropriate spreadsheet model to find the profit based on a given production level and use the spreadsheet model to answer these questions.
(a)
Construct a one-way data table with production volume as the column input and profit as the output. Breakeven occurs when profit goes from a negative to a positive value; that is, breakeven is when total revenue = the total cost, yielding a profit of zero. Vary production volume from 0 to 100,000 in increments of 10,000.…

- Assume that direct labor is a variable cost. The special order would have no effect on the company's total fixed manufacturing overhead costs. The customer would like modifications made to product A90 that would increase the variable costs by $4.20 per unit and that would require an investment of $21,000 in special molds that would have no salvage value. This special order would have no effect on the company's other sales. The company has ample spare capacity for producing the special order. The annual financial advantage (disadvantage) for the company as a result of accepting this special order should be: Brady Corporation has received a request for a special order of 6,000 units of product A90 for $21.20 each.
