The formula for the interest compounded yearly is A = P (1 + r)^n
where A is the final amount, P is the principal amount (initial investment), r is the annual interest rate (in decimal), and n is the number of years.
So for Susan, it would be A = $9,000 (1 + 0.12)^1
A = $9,000 x 1.12
A = $10,080
So at the end of one year, Susan will have $10,080 in the account.
Supposed Susan places $9,000 in an account that pays 12% interest compounded each year assume that no withdrawals are made from the account find the amount in the account at the end of one year
