Answer:
We conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
Step-by-step 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




Divide both sides by -3

and

Therefore, we conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
Cost= (5.50d+6.00p) +6.50
Coefficients: 5.50 and 6.00
Constant: 6.50
Variables: d and p
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
