Question

A teacher has a 2-gallon (32-cup) container of juice. She gives each student 1/2 cup of juice. Which equation represents the amount of juice that remains, y, after x students are served?

Answer 1

y = 32 - 1/2x

example : lets say that there r 30 students.....x = 30
y = 32 - 1/2(30)
y = 32 - 15
y = 17 cups......so 17 cups remain
