The given information provides that the initial investment of a 20-year project is $20,000 and the cash inflow is $4,000 per year. The cost of capital is 17%. To determine the net present value, we need to use the formula of net present value (NPV).NPV = PV of cash inflows - Initial investmentPV of cash inflows can be determined by using the formula:PMT × [1 - (1 / (1 + r)n)] / rWhere,PMT = Cash inflow per periodr = Discount rate/ Cost of capitaln = Number of periodsPutting the values in the formula,PV of cash inflows = $4,000 × [1 - (1 / (1 + 0.17)20)] / 0.17= $4,000 × 6.947 = $27,788.24Now, let's calculate the net present value:NPV = $27,788.24 - $20,000= $7,788.24Since the NPV of the project is positive, it is acceptable. A positive NPV means that the project's cash inflows are greater than the initial investment, and the cost of capital. The NPV provides the estimated value of the future cash inflows of the project in present dollars. The acceptance of the project depends on the decision criterion of the organization. However, a project with a positive NPV is generally acceptable. Therefore, the conclusion is that the project is acceptable.
