Question

baseball fans can buy $7 to sit in the lawn section or $16 for stadium seats. Ticket sales at last night's game totaled $6,920. The number of stadium tickets sold was 20 more than 3 times the number of lawn tickets. In order to find out how many stadium tickets were sold, Kelsey is writing a SYSTEM OF EQUATIONS. What is the second equation?

Answer 1

`7x+16y=6,920...(1)`

`y=3x+20...(2)`

Explanation:

Let x be the number of lawn tickets and y be the number of stadium tickets.

We have been given that baseball fans can buy $7 to sit in the lawn section or $16 for stadium seats. This means that cost of x lawn tickets will be 7x and cost of y stadium tickets will be 16y.

In addition, ticket sales at last night's game totaled $6,920. We can represent this information as:

`7x+16y=6,920...(1)`

We are also told that the number of stadium tickets sold was 20 more than 3 times the number of lawn tickets. We can represent this information as:

`y=3x+20...(2)`

Therefore, our desired system of equations will be:

`7x+16y=6,920...(1)`

`y=3x+20...(2)`
