Question

Mr. Carr paid $64 interest for a two-year loan at 8% simple interest

Answer 1

Answer:

$400

Step-by-step explanation:

The formula for simple interest is i = p * r * t, where r is the annual interest rate as a decimal fraction, p is the principal and t is the time in years.

Here we want to determine what the principal was.  Solving the above equation for p, we get:

           i            $64

p = --------- = -------------- = $400

        r * t       (0.08)(2)
