1. A diesel generator for electrical power can be purchased by a remote community for $480,000 and used for 10 years, when its salvage value is $50,000. Alternatively, it can be leased for $70,000 a year. (Remember that lease payments occur at the start of the year.) The communitys interest rate is 8% (MARR).

1. What is the interest rate for buying versus leasing (IRR)? Which is the better choice?
2. What is the rate of return for the generator using the best financing plan?
