Joan invests $4,000 in an account that earns 3% simple interest. How much will Joan have in the account in 10 years?

Question

Accepted Answer

Use the interest formula (I=Prt) to determine the amount of interest earned, where the principle (P) is 4,000, the rate (r) is .03 (3%) and the time (t) is 10.I= 4,000(.03)(10), orI= $1,200. Add the interest earned to the original amount invested. $4,000 + $1,200 = $5,200.
