Question 1

Roger is planning a party. He needs these ingredients in the following quantities to
make punch:
• 2 quarts orange juice
• 3 cups cranberry juice
• 1 gallon ginger ale
• 1 pint pineapple juice
Roger knows he will need a relatively large container to mix the punch.
Unfortunately, all he can find is a bowl that holds 8 liters of liquid. He is not sure
whether he can fit all of the ingredients in the bowl at the same time.
Use the following measurement equivalents to determine if Roger can use the 8-
liter bowl to mix all the ingredients for the punch. Show your work.
If he can use the bowl, he needs to determine how many liters of liquid could still
fit into the bowl. If he cannot use the bowl, he needs to determine how many extra
liters of liquid there are. Round your answers to the nearest tenth of a liter.
1 liter is about 4.23 cups, 2.11 pints, 1.06 quarts, and 0.26 gallon

To determine whether Roger can fit all the ingredients for the punch in an 8-liter bowl, let's first convert all the quantities of the ingredients to liters. We'll use the provided conversion factors for this calculation.

Ingredients and Their Quantities:

  1. Orange Juice: 2 quarts

    • Conversion: \(2 \text{ quarts} \times 0.946 \text{ liters/quart} = 1.892 \text{ liters}\)
  2. Cranberry Juice: 3 cups

    • Conversion: \(3 \text{ cups} \div 4.23 \text{ cups/liter} \approx 0.708 \text{ liters}\)
  3. Ginger Ale: 1 gallon

    • Conversion: \(1 \text{ gallon} \times 3.785 \text{ liters/gallon} = 3.785 \text{ liters}\)
  4. Pineapple Juice: 1 pint

    • Conversion: \(1 \text{ pint} \div 2.11 \text{ pints/liter} \approx 0.474 \text{ liters}\)

Total Volume Calculation in Liters:

Now we will sum the volumes of all the ingredients:

\[ \text{Total Volume} = \text{Orange Juice} + \text{Cranberry Juice} + \text{Ginger Ale} + \text{Pineapple Juice} \]

\[ \text{Total Volume} = 1.892 + 0.708 + 3.785 + 0.474 \]

\[ \text{Total Volume} \approx 7.859 \text{ liters} \]

Determining Capacity:

Now, we compare this total volume with the capacity of the bowl.

  • Capacity of the bowl: 8 liters
  • Total volume of the ingredients: 7.859 liters

Since \(7.859 \text{ liters} < 8 \text{ liters}\), Roger can use the bowl to fit all the ingredients.

How Many Extra Liters Could Still Fit Into the Bowl:

To find out how many liters could still fit into the bowl:

\[ \text{Extra Capacity} = \text{Capacity of the bowl} - \text{Total Volume} \]

\[ \text{Extra Capacity} = 8 \text{ liters} - 7.859 \text{ liters} \approx 0.141 \text{ liters} \]

Final Answer:

  • Roger can use the 8-liter bowl.
  • Extra capacity in the bowl after adding all the ingredients is approximately 0.1 liters (rounded to the nearest tenth).
