13-9. A lathe costs $56,000 and is expected to result in net cash inflows of $20,000 at the end of each year for three years and then have a market value of $10,000 at the end of the third year. The equipment could be leased for $22,000 a year, with the first payment due immediately. (13.8)

a. If the organization does not pay income taxes and its MARR is 10%, show whether the organization should lease or purchase the equipment.

b. If the lathe is thought to be worth only, say, $18,000 per year to the organization, what is the better economic decision?
