Aaron deposited 591.07 in a savings account that earns 3.7% simple interest. what is aarons account balance after seven years

The formula for this is A=P(1+rt), where A is the amount at the end of whatever time at whatever interest rate, P is the amount you initially deposited, r is the interest rate, and t is the time in years. Ours would look like this:
A = 591.07(1+{.037}{7}) and A = 591.07(1.259) and A = $744.16
