Question 7 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 7%. Initial cost Annual cash inflows Option A $177,000 $72,000 $28,500 $51,000 $0 Option B $268,000 $81,700 $25,600 $0 $7,400 Annual cash outflows Cost to rebuild (end of year 4) Salvage value Estimated useful life 7 years 7 years (a) 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 decimal places as displayed in the factor table provided.) Net Present Value Profitability Index Internal Rate of Return Option A A $ Option B $
