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 6%. Initial cost Annual cash inflows Annual cash outflows Cost to rebuild (end of year 4) Salvage value Estimated useful life Option A Option B $173,000 $267,000 $70,800 $80,100 $29,100 $25,900 $0 $0 $7,000 7 years 7 years $51,500 Your answer is partially correct. Try again. 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 eg (45). Round answers for present value and IRR to o decimal places, e.g. 125 and round profitability index to 2 decimal places, e.g. 12.50. For calculation purposes, use 5 decimai places as displayed in the factor table provided.) Net Present Value Profitability Index Internal Rate of Return Option A 18992 1.10 Option B 40220 1.14 11.68
