Answer: 222 boxes
Step-by-step explanation:
First, find how boxes they sell per hour; 36/3=12
You'll then multiply that by 18, the amount of hours they asked for.
12(18)= 216 Then find how much they make in half an hour. 12/2=6
Add that to the amount you already calculated 216+6= 222
You sold 222 boxes.
