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?
A. y= 32x-1/2
B. y= 1/2x-32
C. y= -1/2x+32
D. y= -32x+1/2

Answer 1

y = 32-1/2x, or C
Our principal is 32, and depending on how many students she serves, x, this will decrease accordingly by 1/2 cup each time
