Yesterday, we took grandma out to lunch at her favorite Noodle Shop. This month, we are keeping a budget of how much we spend eating out.When I reached into my purse, I pulled out my receipt and realized I used the top of the receipt as a gum wrapper. Can I find out how much I spent on lunch? How could I use the math I know?
Let’s have a math chat! Leave me a response to this math happening.

Well, one thing you can do is divide 5.37/2 and get 2.685, which would tell me 10% of the bill was 2.685. If I multiply that by 10 to get 100% of the bill that would be $26.85. That is how much the bill came to. Now I would ask, what did they order?
