Answer:
We conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
Explanation:
Given that
- Some order the chicken dinner for $14
- some order the steak dinner for $17.
- Let 'n' be the number of people who ordered the chicken dinner.
- Let '6-n' be the number of people who ordered the steak dinner.
Thus, the equation becomes
![14n + 17(6-n) = 99](https://img.qammunity.org/2021/formulas/mathematics/high-school/4ayhiafr658xjpbx8bok7c6ef09lbk4e7o.png)
![14n + 102 - 17n = 99](https://img.qammunity.org/2021/formulas/mathematics/high-school/rg4tot069a56x7y0ynv3nxnaevb2wdle54.png)
![-3n = 99 - 102](https://img.qammunity.org/2021/formulas/mathematics/high-school/wew59l4p45d6gv9hktyflcf6pjz5cospc1.png)
![-3n = -3](https://img.qammunity.org/2021/formulas/mathematics/high-school/q8b642ojzuo7pdzbgcaru4wh8btxw7ulxw.png)
Divide both sides by -3
![n = 1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/e1z71dg6mvt8yroo6k7u8edgbpoz4ugpwu.png)
and
![6-n = 6-1 = 5](https://img.qammunity.org/2021/formulas/mathematics/high-school/upjst1bkq3jf4yjrphwvhcvggp0nfm8pei.png)
Therefore, we conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
