Solving Systems of Linear Equations by Elimination 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 y represent the number of students who bought a sandwich. Then the problem can be represented by this system of equations: Answer the questions to solve the problem. Part A Explain what you should do with the two equations to eliminate one of the variables. Space used (includes formatting): 0 / 15000 Part B Find the value of y. Space used (includes formatting): 0 / 15000 Part C Find the value of x. Space used (includes formatting): 0 / 15000 Part D Interpret the solution and check the values in the system.
