Aaron deposited $591.07 in a savings account that earns 3.7% simple interest. what is aaron's account balance after seven years?

 $744.16

Step-by-step explanation:

The formula to find the simple interest is given by :-

, where P is the principal amount, r is rate of interest ( in decimal) and t is time ( in years).

Given : Aaron deposited $591.07 in a savings account that earns 3.7% simple interest.

i.e. P= $591.07 and r= 3.7%=0.037

Then, the simple interest earned in 7 years:-

Then, the  Aaron's account balance after seven years = P+I

=$591.07 +$153.09= $744.16

Hence, Aaron's account balance after seven years = $744.16

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
