Decision at 30%:
| Year | Cash flow | × discount factor @30% | Present value | 
| 0 | $(32,000.00) | 1.000000 | $(32,000.00) | 
| 1 | $ 16,000.00 | 0.769231 | $ 12,307.69 | 
| 2 | $ 20,000.00 | 0.591716 | $ 11,834.32 | 
| 3 | $ 17,000.00 | 0.455166 | $ 7,737.82 | 
| NPV | $ (120.16) | 
Firm should not accept as NPV is negative.
Formula based solution:
NPV @12%= present value of cash inflows – present value of cash outflows
= $16,000/(1+12%)^1 + $20,000/(1+12%)^2 + $17,000/(1+12%)^3 - $32,000 = $10,329.86
NPV @30%= present value of cash inflows – present value of cash outflows
= $16,000/(1+30%)^1 + $20,000/(1+30%)^2 + $17,000/(1+30%)^3 - $32,000 = -$120.16
