Answer:
1100 field-side tickets and 4500 end-zone tickets.
Explanation:
Let x represent number of field side tickets and y represent number of end-zone tickets.
We have been given that the total number of people at a football game was 5600. We can represent this information in an equation as:
![x+y=5600...(1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/a03uulkz8vll01caefs1ebmu330948obat.png)
We are also told that Field-side tickets were 40 dollars and end-zone tickets were 20 dollars.
Cost of x field side tickets would be
and cost of y end-zone tickets would be
.
The total amount of money received for the tickets was $134000. We can represent this information in an equation as:
![40x+20y=134000...(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/tloz49wltfqgouvo0yqs13zsxkidd24oie.png)
Upon substituting equation (1) in equation (2), we will get:
![40x+20(5600-x)=134000](https://img.qammunity.org/2021/formulas/mathematics/high-school/e1j3chvfjk3lqse905kjv3cum60pmfc4ub.png)
![40x+112000-20x=134000](https://img.qammunity.org/2021/formulas/mathematics/high-school/b22or4zamf6nk8k52nvwn40tgv4pqio796.png)
![20x+112000=134000](https://img.qammunity.org/2021/formulas/mathematics/high-school/pd2q937iov915v96bn4s3el9g1qqkzjfrn.png)
![20x+112000-112000=134000-112000](https://img.qammunity.org/2021/formulas/mathematics/high-school/bfx1jk7ei4cibuaj747i5xv9z108tuecdw.png)
![20x=22000](https://img.qammunity.org/2021/formulas/mathematics/high-school/7rbqoi54qbtdmmgtaddltjutib4ak75oqj.png)
![(20x)/(20)=(22000)/(20)](https://img.qammunity.org/2021/formulas/mathematics/high-school/4kjshsrkrevrpjkpkb2g9u1ysp2pmup8b7.png)
![x=1100](https://img.qammunity.org/2021/formulas/mathematics/high-school/e8m0yofjgnsjpxvkiusyjtnuaa3bt40241.png)
Therefore, 1100 field side tickets were sold.
Upon substituting
in equation (1), we will get:
![y=5600-1100](https://img.qammunity.org/2021/formulas/mathematics/high-school/ufb9tpoxw8q7j1zyu03gx7b4w45qwfkep0.png)
![y=4500](https://img.qammunity.org/2021/formulas/mathematics/high-school/7r7dxcxv1te51l8l6b7d8nuv6u37w7ua5a.png)
Therefore, 4500 end-zone tickets were sold.
