You are analyzing a project using an after-tax replacement analysis of the installed system [defender] and a challenger as detailed helow{a1l values are in 51000 units}. The effective state tax rate of 6% is applicable. Assume saluages in the future occur at the estimated amounts and use classical 5L depreciation. (Note: we: is more than yours in service, adopt them" ofservice). {a} Use AW analyses to decide which alternative is better if an after-tax return of 6% per year is required. (Ans. AWn - 5- 41?3. AW: - 5-3432) {b} Would the decision be different if a before-tax replacement analysis Were performed at i-I2% per year? (Ans. AWD =- 5-5046. AW: =- 542%} Defender Challenger First cost. 5 - 20.000 H.000 ADC. Swear |.200 - 1.500 Salvage estimate. 5 2.000 3.000 Market value. 5 [5.000 Life. years I0 3 Years in service 5
