Extended Learning Exercise A company is producing a high-volume item that sells for $0.75 per unit. 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. Assume that nonconforming units can be reworked to specification at an…

An intergated, combined cycle power plant produces 300 MW of electricity by gasifying coal. the captial investment for the plant is $630 million, spread evenly over two years. the operating life of the plant is expected to be 25 years. additionally the plant will operate at full capacity 76% of the time ( downtime is 24% of any given year ) the MARR is 9% per year
a) if this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant ? is it a low-risk venture ?
b) what is the IRR for the plant ? is it profitable ?
