## Algebra 1

In order to solve this problem, we divide the amount of flour by the number of roles used in each situation to determine the amount of flour used per role. Thus, we obtain: A: $1/5$=.2 cups of flour per role B: $7.5/24=.3125$ cups of flour per role C: $10/45= .22$ cups of flour per role Thus, we find that recipe B uses the most cups of flour per role.
