To solve this problem, you need to write an equation using what you know. You know that the total amount of cereal is 18 3/4 cups. You can rewrite this as a fraction:
18 + 3/4
=72/4 + 3/4
=75/4
You also know that a serving feeds one person and each serving has to be at least 3/4 cup. So our equation will be:
(amount of cereal per serving)*(number of people) = (total amount of cereal)
(3/4)*x = (75/4) (where x= number of people you can serve from this box of cereal)
Now we can solve for x by dividing each side by (3/4):
(3/4)x = (75/4)
x = 25
This means that the most people this box of cereal could feed is 25, or answer E.
