A recipe for pancakes serves 4 people and requires 1.5 cups of flour. If the cook wants to make enough pancakes to serve 8 people, how much flour is needed?

Rationale

A) 3 cups of flour is required to make enough pancakes to serve 8 people.

This question involves simple proportional reasoning. If serving 4 people requires 1.5 cups of flour, then serving twice as many people (8 people) would require twice as much flour, which equals 3 cups.

A (3 cups) CORRECT

This is the correct answer. As explained above, if 1.5 cups of flour serves 4 people, then to serve 8 people (twice as many), you would need twice as much flour, which equals 3 cups.

B (5.5 cups) YOUR ANSWER

This answer would imply more than a proportional increase in the amount of flour needed. However, the question implies a direct proportion between the number of servings and the amount of flour required: if the number of servings doubles, the amount of flour should also double.

C (8 cups) YOUR ANSWER

This answer would imply that each person requires 1 cup of flour, which is not consistent with the information provided in the question. According to the original recipe, serving 4 people requires 1.5 cups of flour, not 4 cups.

D (1.5 cups) YOUR ANSWER

This is the amount of flour required to serve 4 people, according to the original recipe. If the number of servings is doubled to 8 people, the amount of flour required would also need to be doubled.

Conclusion

The recipe's requirement of 1.5 cups of flour to serve 4 people sets up a simple proportion. To serve 8 people, which is twice as many, the cook would need twice the amount of flour, or 3 cups. Therefore, the correct answer is A) 3 cups. Other choices suggest non-proportional increases or inconsistencies with the information provided in the question.

A recipe for pancakes serves 4 people and requires 1.5 cups of flour. If the cook wants to make enough pancakes to serve 8 people, how much flour is needed?

A) 3 cups of flour is required to make enough pancakes to serve 8 people.
