Answer

Recipe B

Work Step by Step

We divide the number of dinner rolls by the number of cups of flour to obtain how many cups of flower per dinner roll are present. Recipe A: 5 rolls/1 cup of flour= 5 rolls per cup of flour. Recipe B: 24 rolls/7.5 cups of flour=3.2 rolls per cup of flour. Recipe 3: 45 rolls/ 10 cups of flour=4.5 rolls per cup of flour. Recipe B makes the fewest rolls with one cup of flour, so there is the most flour per roll in Recipe B.
