Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the per month interest rate is equal to 6% divided by 12 divided by 100 = .005
4 months of simple interest = 4 * .005 * 4000 = 80 dollars.
the compound interest earned is equal to 80.6020025 dollars.
the simple interest can be calcullated in a couple of ways as shown below.
.06 * 4000 * 4/12 = 80
.005 * 4000 * 4 = 80
the compound interest is calculated as shown below:
4000 * (1.005)^4 - 4000 = 80.6020025
