Using the simple interest formula, it is found that the total amount of interest is of $60.75.

Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

I(t) = Prt

In which:

  • P is the initial amount.
  • r is the interest rate, as a decimal.

In this problem, the parameters are P = 225, r = 0.09, t = 3, hence:

I = Prt = 225 x 0.09 x 3 = 60.75.
