Here is an unbalanced hanger diagram.

1. If you know each circle weighs 6 grams, what do you know about the weight of each triangle? Explain your reasoning.
2. If you know each triangle weighs 3 grams, what do you know about the weight of each circle? Explain your reasoning.

Match each sentence with the inequality that could represent the situation.

At a skateboard shop:

1. The price tag on a shirt says $12.58. Sales tax is 7.5% of the price. How much will the shirt cost including tax?
