The interest earned will be approximately \$8465.89.

Steps

Step 1 :Define the variables where P is the principal amount which is $14000, r is the annual interest rate which is 12%, n is the number of times that interest is compounded per unit t, in this case, it is compounded quarterly so n is 4, and t is the time the money is invested for which is 4 years.

Step 2 :Calculate the total amount A using the formula \(A = P \times (1 + \frac{r}{n})^{nt}\).

Step 3 :Subtract the principal amount P from the total amount A to find the interest earned.

Step 4 :Round the interest to 2 decimal places.

Step 5 :The interest earned will be approximately \$8465.89.
