What is the annual interest amount calculated for a loan with simple interest?

To determine the annual interest amount for a loan with simple interest, one would typically use the formula for simple interest, which is:

Interest = Principal × Rate × Time

In this scenario, it appears that the chosen answer of $11,137.50 is based on a specific principal amount, an interest rate, and a time period of one year.

When calculating simple interest, the exact values for the principal, the interest rate, and the time period in years play a crucial role. If, for instance, the principal were $100,000 and the interest rate were 11.1375% per annum for one year, then the interest calculated would be:

$100,000 × 0.111375 × 1 year = $11,137.50

This result aligns with the correct answer. It is important to understand that with simple interest, the interest amount remains fixed over time as it is calculated solely on the principal amount, which is different from compound interest where interest can accrue on previously earned interest.

Thus, by applying the relevant numbers into the simple interest formula, $11,137.50 can indeed be obtained as the annual interest amount, highlighting why this option is the correct choice.
