Question

If two adults and three children go to the movies, it costs $31.50. If one adult and five children go to the movies, it costs $35.00. What is the cost of one adult movie ticket?

Answer 1

2(adult cost) + 3(child cost) = 31.5
1(adult cost) + 5(child cost) = 35

Solve the system of linear equations.

Answer 2

Say X is adult cost, Y = child cost.
2X+3Y=31.5
1X+5Y=35
Solve this system of equations to find the answer.

after calculation, adult ticket: X= 5.5
