AAA Trucking in Sydney, Australia uses the following: before-tax MARR = 14% per year, after-tax MARR = 7% per year, and T_e = 50%. Two new spray machine options have the following estimates and will generate the same GI each year.

Machine	A	B
First Cost, $	15,000	24000
Salvage Value, $	3,000	5,000
AOC, $ per Year	3200	1600
Life, Years	10	10

Perform after-tax PW analysis using MACRS depreciation with a 5-year recovery period using a spreadsheet. Assume the machines will be retained for 10 years and then sold at the estimated salvage values. (Please upload your response/solution using the controls below.)
