Question

Beatrice invests $1,410 in an account that pays 3 percent simple interest. How much more could she have earned over a 4-year period if the interest had compounded annually

Answer 1

$7.77

Step-by-step explanation:

The answer would be the difference between compound and simple interest

Simple interest = principal x time x interest

$1,410 x 0.03 x 4 = $169.20

Compound interest = future value - present value

future value = Principal ( 1 + interest)^n

$1,410 ( 1.03)^4 = $1586.96

$1586.96 -$1,410 = $176.97

Difference = $176.97 - $169.20 = $7.77
