Answer:
1,040,000
Explanation:
We can calculate the money will Kalen need to have accumulated at age forty-five by dividing the annual birthday payments by the effective interest.
DATA
Annual birthday payments = A = $40,000
Effective interest = i = 4%
Calculation
Value at age 45 = A / i + Co
Value at age 45 = (40000 / .04) + 40000
Value at age 45 = 1,040,000
Kalen will need to have accumulated money of 1,040,000 at age forty-five, just prior to his first $40,000 birthday payment.
