Rr.5.
A small automotive supply company manufactures fuel gauges for various types of cars.
The company has fixed costs of $1,885,000 per year. The average cost of manufacturing a fuel gauge is $21.88.
The average price the fuel gauge sells for is $48.20
The company manufactures its products 252 days per year. What is the minimum number of fuel guages per
day that the company must produce in order to break even?
For a motor to operate a pump, a design engineer must choose the horsepower. Horsepower rating is a design characteristic that can vary from 10 to 40 horsepower. The motor will cost $120 per year to operate, plus $0.60 per horsepower. The running expenses of such motors will be $0.055 per horsepower-hour divided by the horsepower rating. Each year, 9,000 horsepower-hours will be required.
Determine how much horsepower should be supplied to keep the overall yearly cost to a minimal.
Demonstrate that your entire cost each year has been reduced.

The variable production cost is $0.30 per unit. The company is able to produce and sell 10,000,000 items per year when operating at full capacity. The critical attribute for this product is weight. The target value for weight is 1,000 grams, and the specification limits are set at ±50 grams. The filling machine used to dispense the product is capable of weights following a normal distribution with an average (µ) of 1,000 grams and a standard deviation (σ) of 40 grams. Because of the large standard deviation (with respect to the specification limits), 21.12% of all units produced are not within the specification limits. (They either weigh less than 950 grams or more than 1,050 grams.) This means that 2,112,000 out of 10,000,000 units produced are nonconforming and cannot be sold without being reworked.
