Final answer:
Benny got $12.64 in change after buying pants and a shirt for a total of $27.36 and paying with two $20 bills.
Step-by-step explanation:
Benny went to the mall and paid $12.71 for pants and $14.65 for a shirt. He used two $20 bills, which equals $40. To determine how much money Benny got in change, we must first calculate the total cost of the items and then subtract this amount from the $40 he paid with.
Here's the calculation step-by-step:
Add the cost of the pants and the shirt together:
$12.71 (pants) + $14.65 (shirt) = $27.36 (total cost)
Subtract the total cost from the amount paid with the two $20 bills:
$40.00 - $27.36 = $12.64 (change)
Benny received $12.64 in change after purchasing the pants and shirt.
