At a store, a shirt was marked down in price by $10.00. A pair of pants doubled in price. Following these changes, the price of every item in the store was cut in half. Write two different expressions that represent the new cost of the items,
using s for the cost of each shirt and p for the cost of a pair of pants. Explain the different information each one shows.

The distributive property allows you to say that 3(x − 1) = 3x −
