Answer:
A. 5 1/2 c
Step-by-step explanation:
Sissy recipe will make 6 dozen cookies from 3 cups of flour. That mean, the number of cookie per cup of flour will be:
6 * 12 cookies / 3 cup of flour = 72/3 cookie/c flour = 24 cookie/cup flour.
If she wants to make 128 cookies, the amount of flour she needs will be:
128 cookies / (24 cookie/cup flour)= 5.33 cup flour = 5.5 cup flour (rounded up to 0.5 since its above 0.25)
