Question

Priya has a recipe for banana bread. She uses 5 cups of flour (f) to make 2 loaves of banana bread (b). Andre will follow the same recipe. He will make loaves of banana bread using cups of flour. Which of these equations represents the relationship between b and f?

A) b = (5/2)f
B) b = (2/5)f
C) b = f - 5
D) b = 5f - 2

Answer 1

Priya uses a proportion of 5 cups of flour to make 2 loaves. To find the relationship between loaves (b) and flour (f), we set up the equation b = (2/5)f.

Step-by-step explanation:

The question asks for the equation representing the relationship between the number of loaves of banana bread (b) and the cups of flour used (f) in Priya's recipe. Since Priya uses 5 cups of flour to make 2 loaves of bread, this means for every 1 loaf made, she uses 2.5 cups of flour (5 cups ÷ 2 loaves). Therefore, the number of loaves b is equal to the cups of flour (f) multiplied by 2 and then divided by 5. The equation that best describes this relationship is b = (2/5)f.
