A teacher has a 2-gallon 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 served

y = 32 -1/2x   or y= -1/2x +32  one of this could be answers.

Step-by-step explanation:

First you have to convert 2-gallon into cups for you to have the same measurement units.

2 gallons will give you 32 cups.

Now we know that the teacher has 32 two cups and is giving a half of a cup to students.

We could now write the equation as

y = 32 - 1/2x  or y=  - 1/2x  + 32
