To determine the total amount of water needed for 4 people and 1 pet over 3 days, we will calculate the amount of water for the individuals first, followed by the pet.
Step 1: Calculate Water for People
- Water needed per person per day: 3.2 quarts
- Number of people: 4
- Duration: 3 days
Total water needed for people: \[ \text{Water for people} = 3.2 , \text{quarts/person/day} \times 4 , \text{people} \times 3 , \text{days} \] \[ \text{Water for people} = 3.2 \times 4 \times 3 = 38.4 , \text{quarts} \]
Step 2: Calculate Water for Pet
Let's assume you have a dog that weighs 20 pounds.
- Water needed for dog: 1 oz. per pound \[ \text{Water for dog} = 20 , \text{pounds} \times 1 , \text{oz/pound} = 20 , \text{oz} \]
Convert ounces to quarts: \[ \text{Water for dog} = \frac{20 , \text{oz}}{32 , \text{oz/quart}} = 0.625 , \text{quarts} \]
Step 3: Total Water Calculation
Add the water needed for people and the pet: \[ \text{Total water} = \text{Water for people} + \text{Water for dog} \] \[ \text{Total water} = 38.4 , \text{quarts} + 0.625 , \text{quarts} = 39.025 , \text{quarts} \]
Conclusion
You will need a total of 39.025 quarts of water for 3 days for 4 people and 1 dog weighing 20 pounds.
