The original recipe makes 4 loaves of bread and uses 2 cups of sugar. Let \( x \) represent the amount of flour in cups in the original recipe. The total amount of flour and sugar combined in the original recipe would then be \( x + 2 \) cups.
Since Kendra's adjusted recipe, which makes 1 loaf, calls for 2.12 cups of flour and sugar combined, we can set up the following relationship:
\[ \frac{x + 2}{4} = 2.12 \]
To find \( x + 2 \), we multiply both sides by 4: \[ x + 2 = 2.12 \times 4 \] \[ x + 2 = 8.48 \]
Next, we solve for \( x \) by subtracting 2 from both sides: \[ x = 8.48 - 2 \] \[ x = 6.48 \]
Thus, the amount of flour in the original recipe is 6.48 cups.
