A company is considering investing $17,500 in a heat exchanger. The heat exchanger will last five vears, at which time it will be sold for $2.000, The maintenance cost at the end of the first vear is estimated to be $1.500.
Maintenance costs for the exchanger are estimated to increase by $1,000 per year over its life. As an alternative, the company may lease the equipment for $X per year, including maintenance, with the annual payments to made
at the end of each year.
a. Choose cash flow diagrams of both alternatives
b. For what value of X should the company lease the heat exchanger? The company expects to earn 8% on its investments. Assume end-of-year lease payments.

Suppose we have four mutually exclusive projects, D1, D2, D3, and D4, whose internal rates of return on incremental investment between the projects is given as follows:IRR (Dl - D2) = 27.62%IRR {Dl - D3) = 14.26%IRR {Dl - D4) = 25.24%IRR (D3 - D2) = 30.24%IRR (D2- D4) = 17.34%IRR (D3 - D4) = 16.14%Which project should be selected at MARR 15%?

Buying a new machine will cost $120,000, with a residual value of $12,000 after the machine's useful life of eight years.
