Final answer:
The amount of money in the account just after the 18th deposit would be approximately $4529.
Step-by-step explanation:
To calculate the amount of money in the account just after the 18th deposit, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the future value (the amount of money in the account)
- P is the principal amount (the deposit)
- r is the annual interest rate (4% or 0.04)
- n is the number of times the interest is compounded per year (1 for annually compounded interest)
- t is the number of years
In this case, the principal amount (P) is $2500, the annual interest rate (r) is 4% or 0.04, the number of times the interest is compounded per year (n) is 1, and the number of years (t) is 18. Plugging these values into the formula:
A = 2500(1 + 0.04/1)^(1*18)
Calculating this expression:
A = $2500(1 + 0.04)^18
A = $2500(1.04)^18
A = $2500(1.8116)
A = $4529
Therefore, there would be approximately $4529 in the account just after the 18th deposit.
