Respuesta :

Given:

Total number of tickets = 353

Single ticket = $92

Family ticket = $122

Total sales = $39946

To find:

The number of family tickets.

Solution:

Let x be the number of single tickets and y be the number of family tickets.

Total tickets: [tex]x+y=353[/tex]         ...(i)

Total sales: [tex]92x+122y=39946[/tex]          ...(ii)

Multiply (i) by 92 and subtract the result from (ii).

[tex]92x+122y-92(x+y)=39946-92(353)[/tex]

[tex]92x+122y-92x-92y=39946-32476[/tex]

[tex]30y=7470[/tex]

Divide both sides by 30.

[tex]y=\dfrac{7470}{30}[/tex]

[tex]y=249[/tex]

Therefore, the number of family tickets is 249.
