8. Ellie is evaluating an investment (that Joel told her about) that will provide the following returns at the end of each of the following years: year 1 = $12,500; year 2 = $10,000; year 3 = $7,500; year 4 = $5,000; year 5 = $2,500; year 6 = $1000; and year 7 = $500. Ellie believes that she can earn an annual rate of 8% p.a. on this investment. Assuming Ellie is correct, what is the maximum amount that Ellie should pay for this investment today?
