Final answer:
Roger will make a total of 7.25 quarts of punch after converting all quantities to quarts. However, since this option is not available, the closest approximate answer is 7 quarts, making option (d) the best choice.
Step-by-step explanation:
When calculating the total volume of punch Roger will make, we need to convert all the quantities to the same unit. We'll use quarts as our standard unit since it is a larger unit than cups or pints, and we have a gallon quantity as well.
- 1 gallon = 4 quarts
- 1 pint = 0.5 quarts (since there are 2 pints in a quart)
- 1 cup = 0.25 quarts (since there are 4 cups in a quart)
Now we'll convert:
- 2 quarts of orange juice is already in quarts
- 3 cups cranberry juice = 3 * 0.25 = 0.75 quarts
- 1 gallon ginger ale = 4 quarts
- 1 pint pineapple juice = 0.5 quarts
Add these together: 2 + 0.75 + 4 + 0.5 = 7.25 quarts. However, none of the options provided match this result. If we consider the options available, 7 quarts is the closest approximation to the actual amount, rounding down to the nearest whole number, so option (d) 7 quarts is the most accurate answer given the choices. But it is important to note the exact total volume is 7.25 quarts.
