Consider the following cash flow Year End 0 1-5 Payment $500 $1,000 In computing Fat the end of year 5 at an interest rate of 12%, which of the following equations is incorrect? O A. F = [$500 (A/P, 12%, 5) + $1,000] X (F/A, 12%, 5) OB. F = $500 (F/A, 12%, 6) + $500 (F/A, 12%, 5) OC. F= $500 (F/P, 12%,5) + $1,000 (F/A, 12%, 5) OD. F= $1,000 (F/A, 12%, 5) - $500 (F/P 12%, 5)
