If a family buys a total of 3 one-gallon jugs in a week, how much milk does that provide?

The correct answer is 3 gallons because if a family buys 3 one-gallon jugs of milk, this means they are purchasing three separate containers, each containing one gallon. To find the total amount of milk, you simply multiply the number of jugs by the amount of milk in each jug, which is:

3 jugs × 1 gallon per jug = 3 gallons.

Thus, the total amount of milk the family has is 3 gallons. This straightforward calculation reinforces the concept of multiplication as it applies to measuring quantities and understanding unit rates.
