Final answer:
To calculate the present value of the cash flows for the 20-year project, you need to discount each cash flow using the weighted average cost of capital (WACC).
Step-by-step explanation:
To calculate the present value (PV) of the cash flows, we need to discount them at the firm's weighted average cost of capital (WACC). The PV of the first 10 cash flows of $6,500 each can be calculated as:
PV = $6,500 / (1 + 0.12)1 + $6,500 / (1 + 0.12)2 + ... + $6,500 / (1 + 0.12)10
The PV of the next 10 cash flows of $11,000 each can be calculated in the same way:
PV = $11,000 / (1 + 0.12)11 + $11,000 / (1 + 0.12)12 + ... + $11,000 / (1 + 0.12)20
Add the two PVs to get the total PV of the cash flows. If this total PV is higher than the project cost, which is the initial investment, then the project is considered profitable.
