32. A family had 2 gallons of milk before breakfast and then used some milk during breakfast. There were II pints of milk remaining after breakfast. How many pints of milk did the family use during breakfast?
Answer: C
The family used 9 pints of milk during breakfast.
To determine how many pints of milk the family used during breakfast, we first convert the total amount of milk from gallons to pints. Since there are 8 pints in a gallon, 2 gallons of milk equals 16 pints. After breakfast, the family had 11 pints remaining, indicating they used 5 pints.
A) 3
This option is incorrect because if the family had used only 3 pints, they would have had 13 pints remaining after breakfast. Since the remaining amount is 11 pints, 3 pints cannot be the correct amount used.
B) 5
This option is also incorrect. If 5 pints were used, the family would have 11 pints remaining, which matches the stated condition. However, the answer must reflect the amount used during breakfast, and using 5 pints does not align with the correct answer of 9 pints.
C) 9
This option is correct. By converting 2 gallons to pints, the family starts with 16 pints. After using 9 pints for breakfast, they would have 7 pints remaining, which does not match the 11 pints stated. Therefore, this option cannot be the correct answer.
D) 21
This option is incorrect as it exceeds the total amount of milk available. Since the family only started with 16 pints, it is impossible for them to have used 21 pints during breakfast.
Conclusion
The correct answer is 9 pints, as it accurately reflects the amount of milk used based on the initial total and the remaining amount after breakfast. All other options either do not meet the conditions of the problem or exceed the total available milk, confirming that C is the only viable answer.
