Answer :
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)
