Multiple Choice

At practice, Diego does twice as many push-ups as Noah, and also 40 jumping jacks. He does 62 exercises in total. The equation 2x + 40 = 62 describes this situation. What does the variable x represent?

• The number of jumping jacks Diego does

• The number of push-ups Diego does

• The number of jumping jacks Noah does

• The number of push-ups Noah does

How do I solve the equation:  $25-3x=40$  

How do I solve the equation:  $\frac{1}{3}\left(x-10\right)=-4$  

Multiple Choice

A food pantry is making packages. Each package weighs 64 pounds.

Here are two situations. For each situation, write and solve an equation, using x as the variable to represent the weight of one bag of rice. If you get stuck, try drawing a diagram.

Situation 1: Each package contains 4 boxes. Each box contains a 7-pound bag of beans and a bag of rice. The bags of rice are all identical.

• 4(x+7)=64

• 4x+7=64

For a school fundraiser, Elena will make T-shirts. She will order T-shirts and print graphics on them. Elena must spend $349 on a printing machine and $4.80 per shirt for the blank shirts, ink, and other supplies.

• Let's make an expression to fit this scenario!

 $349+4.80s$  

How much would it cost to make 20 shirts, 40 shirts, 60 shirts?

How many shirts could she make with $1000?
