To find the amount of flour in the original recipe, we first need to determine the total amount of flour and sugar in the original recipe.
The original recipe makes 4 loaves and uses 2 cups of sugar. Since Kendra is making only 1 loaf, we can scale down the sugar accordingly. The original recipe uses:
- Sugar in the original recipe: 2 cups
- For 1 loaf: \( \frac{2 \text{ cups}}{4} = 0.5 \text{ cups}\)
Now, we know from Kendra's adjusted recipe that the total amount of flour and sugar combined for 1 loaf is 2.5 cups.
Let \( F \) be the amount of flour in the original recipe for 1 loaf. Then, the equation for the total amount of flour and sugar for 1 loaf is:
\[ F + 0.5 \text{ cups of sugar} = 2.5 \text{ cups} \]
To find \( F \), we can rearrange the equation:
\[ F = 2.5 \text{ cups} - 0.5 \text{ cups} = 2 \text{ cups} \]
Thus, the amount of flour in the original recipe is \( 2 \) cups.
Therefore, the original recipe uses 2 cups of flour.
