Here are two stories:

• A family buys 6 tickets to a show. They also each spend $3 on a snack. They spend $24 on the show.

• Diego has 24 ounces of juice. He pours equal amounts for each of his 3 friends, and then adds 6 more ounces for each.

Here are two equations:

• 3(x + 6) =24

• 6(x + 3) =24

Which equation represents which story?

Below is a set of data about temperatures. The range of a set of data is the distance between the lowest and highest value in the set.

9^oC, -3^oC, 22^oC, -5^oC, 11^oC, 15^oC.

What is the range of these temperatures?

A store is having a 25% off sale on all shirts.

Show two different ways to calculate the sale price for a shirt that normally costs $24.
