6700 dollars is placed in an account with an annual interest rate of 8%. How much
will be in the account after 24 years, to the nearest cent?

Turn 8% into a decimal which is 0.08
Multiply the 0.08 by the 6700 you have in the account to get $536. This means every year $536 will be added to the account. You need to multiply this by 24 to see how much money will be added after 24 years.
24 x 536 = $12,864, add this to your original 6700 dollars.
6700 + 12,864 = $19,564
