Activity 2 How Much Milk Was Used?

The bakery that sells banana bread also sells fresh milkshakes. Each serving uses liters of milk.
Here are five descriptions of the milkshakes sold in a week and five expressions that represent the liters of milk used.

Match each description to an expression that represents it.

2. On Tuesday, two customers bought 4 servings of milkshake each. How much milk was used?

3. On Wednesday, four customers bought 2 servings of milkshake each. How much milk was used?

4. On Thursday, two customers each bought a serving of milkshake. They placed the same order three more times for their friends that day. How much milk was used?

5. On Saturday, four friends each purchased a serving of milkshake for breakfast. They came back for the same after dinner. How much milk was used?
