Answer:
NPV = $45,472.30
Explanation:
The NPV is the difference between the PV of cash inflows and the PV of cash outflows. A positive NPV implies a good investment decision and a negative figure implies the opposite. Â
NPV of an investment: Â
NPV = PV of Cash inflows - PV of cash outflow Â
PV of cash inflows = 45,000  ×1 .1^(-1) +  45,000 × 1.1^(-2) +  40,000 × 1.1^(-3) +  40,000 × 1.1^(-4)= 135,472.3038
Initial cost = 90,000
NPV = 135,472.3038 Â - 90,000 =$45,472.3038
NPV = $45,472.30
