Each of 36 students at a school play bought either a cup of orange juice or a
sandwich. A cup of orange juice costs $1 and a sandwich costs $3. The total
amount collected was $76. How many students bought orange juice, and how many
bought a sandwich?
Let x represent the number of students who bought a cup of orange juice and
represent the number of students who bought a sandwich. Then the problem can be
represented by this system of equations:
X+ 3y= 76
X+ y = 36
