Final answer:
To obtain a 10% annual return on his investment, the original owner would have to receive $8,832 in 1987.
Step-by-step explanation:
To calculate the price that the original owner would have to receive in 1987 to obtain a 10 percent annual return on his investment, we can use the concept of compound interest. Since the car was purchased in 1967 and held for 20 years, we need to calculate the future value of the initial investment of $4000.
The formula for compound interest is:
FV = PV × (1 + r)^n
Where FV is the future value, PV is the present value (initial investment), r is the annual interest rate (10% in this case), and n is the number of years.
Using this formula, we can calculate:
FV = $4000 × (1 + 0.10)^20
= $4000 × 2.208
= $8,832
Therefore, the original owner would have to receive $8,832 in 1987 to obtain a 10 percent annual return on his investment.
