Answer:the cost of each adult ticket is 19.7
Step-by-step explanation:
Let a represent the cost of each adult ticket.
The cost of each student ticket is 10.25.
Me Mccory buys 12 students tickets and 12 adult tickets to a play. The total amount she pays for the tickets is 359.40. This means that
12 × 10.25 + 12y = 359.40
123 + 12y = 359.4
Subtracting 123 from the left hand side and the right hand side of the equation, it becomes
123 - 123 + 12y = 359.4 - 123
12y = 236.4
Dividing the left hand side and the right hand side of the equation by 12, it becomes
12y/12 = 236.4/12
y = 19.7
