Libby has 160 quarters in her piggy bank. She has to pay $35 to replace her sister’s dress that she borrowed and ruined. After replacing the dress, how many quarters will Libby have left? Think carefully first, then make a decision:
There are 4 quarters in every dollar, so $35 x 4 = 140 quarters. Libby has 160 quarters – 140 quarters to repay her sister = 20 quarters left. So, the answer is 20.
