Answer:
annual increase in revenues = $249,000 - $74,000 = $175,000
then they grow by 2% per year
depreciable value = $369,000 - $49,000 = $320,000
depreciation expense per year = $320,000 / 5 = $64,000
initial investment = $369,000 + $12,000 = $381,000
corporate tax rate = 39%
cash flow year 0 = -$381,000
cash flow year 1 = [($175,000 - $64,000) x (1 - 39%)] + $64,000 = $131,710
cash flow year 2 = [($178,500 - $64,000) x (1 - 39%)] + $64,000 = $133,845
cash flow year 3 = [($182,070 - $64,000) x (1 - 39%)] + $64,000 = $136,023
cash flow year 4 = [($189,426 - $64,000) x (1 - 39%)] + $64,000 = $140,510
cash flow year 5 = [($193,214 - $64,000) x (1 - 39%)] + $64,000 + $49,000 + $12,000 = $203,821
