1. compute the machine's internal rate of return.

2. compute the machine's net present value. Use a discount rate of 14%.

3. compute the internal rate of return to the nearest whole percent.

i need step by step explanation plus answer thanks.

Henrie's Drapery Service is investigating the purchase of a new machine for cleaning and blocking drapes. The machine would cost $137.280. Including freight and Installation. Henrle's has estimated that the new machine would increase the company's cash inflows, net of expenses, by $40,000 per year. The machine would have a five-year useful life and no salvage value. (Hint Use Microsoft Excel to calculate the discount factor(s).) Required: 1. Compute the machine's Internal rate of return. (Do not round Intermediate calculations and round your final answer to nearest whole number.) Internal rate of return % 2 Compute the machine's net present value. Use a discount rate of 14% (Do not round Intermediate calculations and round your final answers to the nearest dollar amount.) Net present value 3. Suppose that the new machine would increase the company's annual cash inflows. net of expenses by only $37.150 per year. Under these conditions, compute the Intemal rate of return to the nearest whole percent. (Do not round Intermediate calculations and round your final answer to nearest whole number.) -real rate of retum
