I'll be glad to check your answer.

To find the annual interest rate charged on a loan, we can use the formula for simple interest:

Simple Interest = Principal × Rate × Time

In this case, the principal is $6300, the simple interest is $1039.50, and the time is 2 years.

Substituting these values into the formula, we get:

$1039.50 = $6300 × Rate × 2

Now let's solve for the rate:

Dividing both sides of the equation by ($6300 × 2), we have:

Rate = $1039.50 / ($6300 × 2)

Rate = $1039.50 / $12600

Rate ≈ 0.082143

To convert this decimal to a percentage, we can multiply by 100:

Rate ≈ 0.082143 × 100

Rate ≈ 8.2143%

Therefore, the annual interest rate charged on the 2-year loan of $6300 is approximately 8.2143%.
