8-40. Your company must obtain some laser measurement devices for the next six years and is considering leasing. You have been directed to perform an actual-dollar after-tax study of the leasing approach. The pertinent information for the study is as follows: Lease costs: First year, $80,000; second year, $60,000; third through sixth years, $50,000 per year. Assume that a six-year contract has been offered by the lessor that fixes these costs over the six-year period. Other costs (not covered under contract): $4,000 in year-zero dollars, and estimated to increase 10% each year. Effective income tax rate: 40%. (8.7)

a. Develop the actual-dollar ATCF for the leasing alternative.

b. If the real MARR (ir) after taxes is 5% per year and the annual inflation rate

(f) is 9.524% per year, what is the actual-dollar after-tax equivalent annual cost for the leasing alternative?
