Your office is considering one of two models of machinery that have unequal useful lives. The first has a 6-year useful life, a cost today of $320,000 and after-tax operating expenses of $30,000 each year (i.e., at t = 1, t = 2, 3, 4, 5, & 6). What is the equivalent annual annuity (EAC) for this machine if the cost of capital is 14%?
