To find the annual deposits the father needs to make, we can use the formula for the future value of an ordinary annuity:
Future Value = Payment * [(1 + Interest Rate)^Time - 1] / Interest Rate
Where:
- Future Value is the desired amount ($62,649)
- Payment is the annual deposit
- Interest Rate is the annual interest rate (8% or 0.08)
- Time is the number of years (13 years)
Using the given information, we have:
Future Value = $62,649
Interest Rate = 0.08
Time = 13 years
Now we can rearrange the formula to solve for Payment:
Payment = Future Value * (Interest Rate / [(1 + Interest Rate)^Time - 1])
Payment = $62,649 * (0.08 / [(1 + 0.08)^13 - 1])
Calculating this, the father needs to make annual deposits of approximately $4,393.25 in order to accumulate $62,649 over a period of 13 years, considering an 8% annual interest rate compounded annually.
