The compound interest formula is A = P(1 + ) where P is the principal, A is the ending amount, r is the annual interest rate, m is the number of compounding periods, and is the number of years. Billy invested $8,000 in a savings account paying 3.5 % interest,
compounded monthly. How much will Billy have after 12 years?
