Answer:
After her 18th birthday the balance will be $41,301
Explanation:
Balance right after the 18th birthday is calculated using the formula for future value of annuity
FV = [tex]PMT \times \frac{(1+i)^{n}-1}{i}[/tex]
Annual payment PMT = 1,000
Interest rate i = 0.09
Deposits are made for 18 years: n = 18
The balance in her account will then be:
FV = 1,000 * ( 1.09^18 - 1 ) / 0.09
= $41,301
