Final answer:
To find how much flour is in each loaf of raisin bread, subtract the amount used for the pretzel from the total amount of flour. Then, divide the remaining flour by the number of loaves.
Step-by-step explanation:
To find how much flour is in each loaf of raisin bread, we first need to determine how much flour is left after making the pretzel. Alana has 12.5 cups of flour, and the pretzel requires 2.5 cups, so she has 12.5 - 2.5 = 10 cups of flour left.
Next, we divide the amount of flour left by the number of loaves of raisin bread she is baking. Since she is making 4 loaves, we divide 10 cups by 4 to find that there is 2.5 cups of flour in each loaf of raisin bread.
