Answer:
cash flow year 0 = -$3,200,00 - $320,000 = -$3,520,000
cash flow year 1 = [($2,400,000 - $700,000 - $800,000) x (1 - 22%)] + $800,000 = $1,502,000
cash flow year 2 = [($2,400,000 - $700,000 - $800,000) x (1 - 22%)] + $800,000 = $1,502,000
cash flow year 3 = [($2,400,000 - $700,000 - $800,000) x (1 - 22%)] + $800,000 = $1,502,000
cash flow year 4 = [($2,400,000 - $700,000 - $800,000) x (1 - 22%)] + $800,000 + [$350,000 x (1 - 22%)] + $320,000 = $2,095,000
