Baird Brothers Construction is considering the purchase of a machine at a cost of $122,000. The machine is expected to generate cash flows of $20,700 per year for thirteen years and can be sold at the end of thirteen years for $10,500. The discount rate is 10%. Assume the machine would be paid for on the first day of year one, but that all other cash flows occur at the end of the year. Ignore income tax considerations. (FV of $1, PV of $1, FVA of $1, and PVA of $1). (Use appropriate factor(s) from the tables provided.) a. Calculate the present value of net cash flows. b. Should Baird Brothers Construction purchase the machine? Complete this question by entering your answers in the tabs below. Required A Required B Calculate the present value of net cash flows. (Do not round intermediate calculations. Round final answer to the nearest whole dollar.) Present value of net cash flows Required A Required B >
