For the cash flows shown, determine the incremental cash flow between machines B and A for (a) year 0. (b) in year 3, and (c) in year 6. Machine B First Cost, $ -15,000 -25,000 AOC, S/year -1,600 400 Salvage value, $3,000 6,000 3 4. Life, years (a) = -10000 (b) = -1800 (c) = 1200 (a) = -10000 (b) = 13200 (c) = 13200 (a) = -10000 (b) = 13200 (c) =6000 (a) = -10000 (b) = 13200 (c) = 4200
