Order of Operations Party

Imagine you want to throw a party.  What will you need to buy?  If I wanted to throw a party for our math class (since everybody mastered Order of Operations), here is what I would need:


I know that each of these items costs $5.  How much will the party cost?

Well, I know that I need to buy 2 veggie trays.  For the next three items, I need 4 each.  Here's what that looks like in numbers and operations:

5(2 + 3 x 4)

In your journal, use order of operations to find out how much this party would cost.  Circle your answer.
