Answer:
$39
Step-by-step explanation:
He has $115 total, and he spent it on shirts and pants
First, find how much money he spent
Shirts:
5 shirts at $11 each
5*11=55
$55
Pants:
$21
To find how much he has left, subtract what he spent from the total amount of money he had to begin with
total-shirts-pants
115-55-21=39
He has $39 left to buy more clothes
