Randy deposits $7,540 in a bank account that pays 4.5 percent simple interest. If he doesn't change the principle, what will his balance be in 10 years?
The formula for Simple Interest is Interest= Principle x Rate x Time. You fill in the formula- ?= 7540 x 4.5% x 10. Then, you turn the rate into a fraction- 0.045. Fill in the formula again, 7540 x 0.045 x 10, you multiply. 7540 x 0.045 x 10 = 3393. The interest after ten years will be $3393.
