You invested $1,330 in an account that pays 4 percent simple interest. How much more could you have earned over a 4-year period if the interest had compounded annually?Group of answer choices$12.58$12.46$13.11$22.59$13.77

To solve this problem, we first need to calculate the simple interest and then the compound interest.

1. Simple Interest: The formula for simple interest is I=Prt, where P is the principal amount, r is the rate of interest, and t is the time. So, I = 1330 * 0.04 * 4 = $212.8

2. Compound Interest: The formula for compound interest is A=P(1+r/n)^(nt), where P is the principal amount, r is the rate of interest, n is the number of times interest applied per time period and t is the time. Here, interest is compounded annually, so n=1. So, A = 1330 * (1 + 0.04/1)^(1*4) = $1554.88

The interest earned is A-P = $1554.88 -$1330 = $224.88

3. Difference: The difference between the compound interest and the simple interest is $224.88 -$212.8 = $12.08

So, you could have earned $12.08 more over a 4-year period if the interest had compounded annually. However, this option is not available in the given choices. There might be a slight variation due to rounding off the values. The closest answer to this is$12.46.
