Answer:

The theater sells 47 adult tickets and 37 children tickets

Step-by-step explanation:

Let

x = number of adult tickets sold

y = number of children tickets sold

1. A local dinner theater sells adult tickets for $105 each, then they get $105x selling x adult tickets and each children tickets for $60 each, then they get $60y selling y children tickets.

They make a total of $7,155, so

[tex]105x+60y=7,155[/tex]

2. In total, the theater sells 84 tickets, so

[tex]x+y=84[/tex]

3. Express y from the second equation

[tex]y=84-x[/tex]

and substitute it into the first equation:

[tex]105x+60(84-x)=7,155\\ \\105x+5,040-60x=7,155\\ \\105x-60x=7,155-5,040\\ \\45x=2,115\\ \\x=47\\ \\y=84-x=84-47=37[/tex]
