By performing a change of units, will see that the recipe only makes 21 cups of punch, so it is not enough for the whole class.
Will the recipe make enough punch?
The class wants to make, at least, 24 cups of punch.
The recipe that they will use needs:
1 gal of ginger ale, 1 quart of orange juice, and 1 cup of lemon juice.
Let's write all of these quantities in cups, to see how many cups of punch this recipe makes:
- 1 gal = 16 cups.
- 1 quart = 4 cups
Then the recipe mixes:
16 cups of ginger ale, 4 cups of orange juice, and 1 cup of lemon juice, then this recipe makes:
16 cups + 4 cups + 1 cups = 21 cups
This is not enough for the 24 students.
