Brooks Clinic is considering investing in new heart-monitoring equipment. It has two options. Option A would have an initial lower cost but would require a significant expenditure for rebuilding after 4 years. Option B would require no rebuilding expenditure, but its maintenance costs would be higher. Since the Option B machine is of initial higher quality, it is expected to have a salvage value at the end of its useful life. The following estimates were made of the cash flows. The company's cost of capital is 5%. Initial cost Annual cash inflows Annual cash outflows Cost to rebuild (end of year 4) Salvage value Estimated useful life Option A $179.000 $71.700 $30,200 $50,700 SO 7 years Option B $283,000 $81.100 $25,800 $0 $7.900 7 years Click here to view PV table Compute the (1) net present value, (2) profitability index, and (3) internal rate of return for each option. (Hint: To solve for internal rate of return, experiment with alternative discount rates to arrive at a net present value of zero.) (If the net present value is negative, use either a negative sign preceding the number eg -45 or parentheses es (45). Round answers for present value and IRR to decimal places, e.g. 125 and round profitability index to 2 decimal places, eg. 12.50. For calculation purposes, use 5 decimal places as displayed in the factor table provided) Net Present Value Profitability Index Internal Rate of Return Option A $ 9 Option B S 90 e Textbook and Media
