Keith went to the mall on Saturday to buy clothes. He paid $13.05 on a shirt and $9.40 on a jacket with two $20 bills. How much money did Keith get in change?
All you have to do to find the answer is add $13.05 and $9.40 to get $22.45. Then, it says he paid with two $20 bills, which is $40. So after that, all you do is subtract $40-$22.45.
