Answer:

Pavilion seats: 1000

Lawn seats: 600

Step-by-step explanation:

Let p represent tickets for pavilion seats and l represent that of lawn seats

Then the total number of tickets is

[tex]p + l = 1600....(1)[/tex]

The total revenue is

[tex]25p + 15l = 34000....(2)[/tex]

We make p the subject in the first equation:

This implies that:

[tex]p = 1600 - l.....(3)[/tex]

Put equation (3) into equation (2).

This gives us:

[tex]25(1600 - l) + 15l = 34000[/tex]

Expand to get:

[tex]40000 - 25l + 15l = 34000[/tex]

Group similar terms:

[tex] - 25l + 15l = 34000 - 40000[/tex]

Simplify to get

[tex] - 10l = - 6000[/tex]

[tex] \implies \: l = 600[/tex]

Put l=600 into equation (3) to get:

[tex]p = 1600 - 600 = 1000[/tex]

Therefore 1000 pavilion seats and 600 lawn seats were sold.
