Question

Michelle invests her money in an account earning simple interest. What can she expect to happen to the balance of her account. A. The balance will increase linearly. B. The balance will increase more and more each year, but it will not be linear. C. The balance will increase for a while and then stay the same. D. The balance will stay the same.

Answer 1

A. The balance will increase linearly.

Explanation:

Simple interest is computed on the amount of the original balance. The amount of interest is proportional to the interest rate and the time period.

For a constant interest rate, the amount of interest added to the account is a linear function of time. So, the total balance is a linear function of time.
