and $7 for children. The dance company sold 253 tickets, and the total receipts were $2,771. How many adult tickets and how many child tickets were sold?

Let the number of adult tickets sold be x
and the number of child tickets sold be y
Given:
Cost of tickets for adults = $15
Cost of tickets for children = $7
Total number of tickets sold = 253
Total receipts = $ 2771
Solution
The sum of the number of adults and child tickets is:
[tex]x\text{ + y = 253}[/tex]The receipt for adults :
[tex]=\text{ 15x }[/tex]The receipts for children:
[tex]=\text{ 7y}[/tex]The sum of the receipts for adults and children is the total receipts:
[tex]15x\text{ + 7y = 2771}[/tex]Solving the equations simultaneously, we can obtain x and y:
[tex]\begin{gathered} x\text{ + y = 253} \\ 15x\text{ + 7y = 2771} \end{gathered}[/tex]The values of x and y after solving simultaneously are :
[tex]\begin{gathered} x\text{ = 125} \\ y\text{ = 128} \end{gathered}[/tex]Answer: The number of adults tickets = 125
The number of child tickets = 128
