Question

Tickets to a movie cost $11 for adults and $7 for students. A group of friends purchased 8 tickets

for $76. Write a system of equations to represent the situation. How many adult tickets and
student tickets were purchased

Answer 1

5 Adult tickets were purchased and 3 student tickets were purchased.

Explanation:

Write the problem as an equation like this

11x+7x=76

Now make an equation for the number of purchased tickets. Let x be adult and y be students.

x+y=8

Rewrite x + y = 8 as y = -x +8

Substitute y = -x + 8 into the first equation for y.

11x+7(-x+8)=76

11x+(-7x)+56=76

solve for 11x+(-7x)

4x+56+76

subtract 56 from both sides

4x=20

Divide both sides by 4

X=5

x + y = 8

5 + y = 8

y = 3

5 Adult tickets were purchased and 3 student tickets were purchased.
