Answer:
$1556.88
Step-by-step explanation:
<em>Since Stephanie is earning </em><u><em>simple interest</em></u><em> and not compound interest, we can multiply her interest rate for each month by how many months we are calculating for.</em>
0.035 x 5 = 0.175
<em>Then multiply that by her current balance but change the </em><em>0</em><em> in front of the </em><em>0.175</em><em> to a </em><em>1</em><em> to reduce the number of steps we have to take. (It automatically adds what is earned in interest to her current balance.)</em>
1.175 x 1325 = 1556.875
