Calculate the difference between the amounts of interest from the two options.

Let's calculate the difference in interest.

c) iii) To calculate the difference between the amounts of interest from the two options:
From the previous calculations:
Interest from Option A (Simple Interest) = $72.00 Interest from Option B (Compound Interest) =$74.92

Step 1: Subtract the smaller interest amount from the larger interest amount.

$$\text{Difference} = \text{Interest from Option B} - \text{Interest from Option A}$$

$\text{Difference} = \$74.92 - \$72.00$ $\text{Difference} = \$2.92$ The difference between the amounts of interest from the two options is \boxed{\mathbf{\2.92}}$.
