Answer:
2%
Step-by-step explanation:
Simple Interest means that it is calculated ONCE on the original amount in the account.
To figure out the rate of interest:
1. Figure out how much actual interest was earned by taking the balance in the account NOW less the amount originally put in. So $7170.60 - $7030 = 140.60.
2. Divide the 140.60 by the original amount: 140.60 / 7030 = .02 or 2%
