Answer :
Answer:
$37,680.95
Step-by-step explanation:
You want the value of an investment earning a 9% rate of return, given that it pays $12500, 10000, 7500, 5000, 2500, 0, and 12500 at the end of each of the following 7 years.
Present value
The present value of the series of payments is conveniently calculated by a spreadsheet formula. The attachment shows the result.
The present value of any given payment is given by ...
PV = P(1.09^-t)
where PV is the present value of payment P received after t years. The 1.09 represents the expected earnings of 9% on the value.
The present value of the series of payments is the sum of the present values of each of them.
The investment is worth $37,680.95.

Additional comment
The spreadsheet formula used is =NPV(9%, [range of payment data]), where [range of payment data] refers to the cells containing the 7 payments.
