One of the expert tutor answered the following question:

2. Later, the company is considering the purchase of machinery and equipment to set up a line to produce a combination washer-dryer. They have given you the following information to analyze the project on a 5-year timeline:

Initial cash outlay is $150,000, no residual value.

Sales price is expected to be $2,250 per unit, with $595 per unit in labor expense and $795 per unit in materials.

Direct fixed costs are estimated to run $20,750 per month.

Cost of capital is 8%, and the required rate of return is 10%.

They will incur all operational costs in Year 1, though sales are expected to be 55% of break-even.

Break-even (considering only direct fixed costs) is expected to occur in Year 2.

Variable costs will increase 2% each year, starting in Year 3.

Sales are estimated to grow by 10%, 15%, and 20% for years 3 - 5.

They have asked you to calculate:

The product's contribution margin

Break-even quantity

NPV

IRR

Once you have determined these amounts, they have asked that you present the information, describe how you performed your calculations, and explain what the results mean.

After you have completed the calculations and presented your work, management makes the investment.

Explain how the project analyses do or do not support this decision.

In either case, what are the factors that should have been considered in management's decision?

My question: The expert tutor uses the cost of capital, which is 8%, instead of the required rate of return, which is 10% in the computation. Please explain the reason why?

Thank you
