Charlie has a project for which he had determined a present worth of $56,459. He now has to calculate the IRR for
the project, but unfortunately he has lost complete information about the cash flows. He knows only that the project has
a five-year service life and a first cost of $200,000, that a set of equal cash flows occurred at the end of each year, and
that the MARR used was 10 percent. What is the IRR for this project?

A company is considering investing $17,500 in a heat exchanger. The heat exchanger will last five years, at which time it will be sold for $2,000. The maintenance cost at the end of the first year 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.
