Hi Dazzmine,
I am not sure if you received an answer for this problem, but just in case you didn't:
Simple Interest (I) is calculated by multiplying the amount borrowed or deposited (P) by the interest rate (r) (as a decimal) by the time (t) (in years).
The equation used to represent this is:
I = P • r • t
I = 5709 • 0.045 • 3
I = $770.72
The interest would be $770.72
