Johnnys Lunches is considering purchasing a new, energy-efficient grill. The grill will cost $43,000 and will be depreciated straight-line over 3 years. It will be sold for scrap metal after 5 years for $10,750. The grill will have no effect on revenues but will save Johnnys $21,500 in energy expenses. The tax rate is 30%. Required: a. What are the operating cash flows in each year (0-5)? b. What are the total cash flows in each year (0-5)? c. Assuming the discount rate is 12%, calculate the net present value of the cash flow stream. Should the grill be purchased?
