Question

For how many weeks would the class need ti sell cookies in order to earn $5000

Answer 1

So we know that every 3 weeks they make $500 dollars.

We're trying to find out how many weeks will make $5000 dollars.

Let's start out simple.

3 weeks = $500.
5 x 10 is 50, so if we multiply 500 by 5, you get 5000.
Do the same thing on the other side. (3 weeks) This equals 30.

So it will take 30 weeks to make $5000 dollars.
