Answer:
$169,303.35
Explanation:
Present value is found by discounting the cash flows at the discount rates.
Present value can be calculated using a financial calculator:
Cash flow each year from year one to fourteen = $21,000
Cash flow in year 15 = $21,000 + $40,000 = $61,000
Discount rate = 10%
NPV = $169,303.35
