Teachers, save “Can you break a ten?” to assign it to your class.

Ok boys and girls. I need your help. I'm at the grocery store getting ready to leave. I look down and see that I have $35 dollars in my wallet, made up of three 10s and five 1s. Can you help me decide if you should ask to exchange a 10 dollar bill for ten one dollar bills before go to school tomorrow to pay for Girl Scout Cookies. There are four pages with a different amount that you owe. In all the questions, imagine you start with $35 dollars.
