You want to save for a brand-new car. You put the $5,000 your Grandma gave you when you graduated in an account that pays 6% interest and is compounded monthly. How much will you have at the end of five years? Hint: use Compound Interest formula A = P (1 +r/n)nt.

$18000

Step-by-step explanation: Since your interest rate is "per month" and you gave your time interval in years we need to convert your time interval into "month" as well. Do this by multiplying your time, 5 year(s), by 12, since there's 12 months in 1 year. So, t is 60 month time periods. To find the simple interest, we multiply 5000 × 0.06 × 60 to get that the interest is 18,000.
