Last Week's Brains Problem

Imagine you start your lemonade stand with 1,959 cups of lemonade. You sell 42 cups of lemonade, but then 7 cups are returned to you because they have bugs in them. Ew! How many cups of lemonade do you end up with (including the buggy ones that are returned to you)?

Answer

Math Strategies Used: Make an organized list and Write an equation

You start with 1,959 cups.
You sell 42 cups.
You get back 7 cups.

So 1,959 – 42 + 7 = 1,924 cups of lemonade.

That's a lot of lemonade!
