Final answer:
To calculate the amounts that must be invested each year for a target amount, you can use the formula for future value of an ordinary annuity.
Step-by-step explanation:
To calculate the amounts that must be invested each year in order to accumulate $200,000 after 25 years, we can use the formula for future value of an ordinary annuity. For 8% compounded annually, the formula is:
$200,000 = X * (1 + 0.08)^25 - 1 / 0.08
For 10% compounded annually, the formula is:
$200,000 = X * (1 + 0.1)^25 - 1 / 0.1
Solving these equations will give you the amounts that must be invested each year.
