Exercise 12-6 (also in your book at end of chapter) BSU Inc. wants to buy a new machine for $29,300 plus $1,500 for installation costs.

NEW machine will decrease operating costs by $7,000 each year of its useful life. The straight- line depreciation will be used for the new machine for a 6-year period with no salvage value. Instructions (a) Determine the cash payback period. (b) Determine the approximate internal rate of return. (c) Assuming a required rate of return of 10%, should the new machine be purchased? (a) (What amount + or - what amounts) Total "net investment = 29,300 + 1,500 - 2,000 Annual net cash flow = Payback period 28,800 / 7,000 (* "net" means after you add and or subtract pertinent amounts (answer) 28,800 7000 4.11 years Present Value 28,800 (b) Net annual cash flows Less capital investment Net present value 11.98% Yes, the new machine should be purchased because the IRR IS 11.98%, meaning it is greater than BSU Inc required rate of return which is only 10% & another reason is because the NPV is positive. your decision...
