Answer:
[tex]2x + 5y = $3.15[/tex]
Step-by-step explanation:
2x + 5y = $3.15
There are 2 adults, and 5 children.
The symbol 'x' is used to represent the price of one adult ticket.The symbol 'y' is used to represent the price of one child's ticket.
In all, their total was $3.15
[tex]x = 2y[/tex]
The text explains that one adult ticket costs twice as much as a child's ticket.
If x = 2y then 2x = 4y.
Doubling one side would double the other.
So, 4y + 5y = 9y
9y = 3.15
[tex] \frac{9y}{9} = \frac{3.15}{9} [/tex]
Price of One Child Ticket
[tex]y = 0.35[/tex]
Price of One Adult Ticket
[tex]x = 0.70[/tex]
To find the adult price, just multiply the child's ticket price by 2 (two).
