<span>the answer is C) 10; it represents the hourly wage for the worker</span>
First, let's make some variables then make an expression.
Let x = the number of pizzas
Let y = the number of salads
Then 12x = the price for x pizzas
Then 2y = the price y pizzas
Now we can make our expression.
We combine the costs for the pizzas and salads and delivery charge is added.
12x + 2y + 3
Now we have our expression. Replace the x with how many pizzas you bought and replace the y with how many salads you bought.
How much would 6 pizzas and 3 small salads would cost?
12(6) + 2(3) + 3 =
72 + 6 + 3 =
78 + 3 =
81
The answer to this question is $81.

Answer:
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
Step-by-step explanation:
Let us suppose r be the total number of meals eaten in a restaurant
Let us suppose c be the total number of meals eaten in a car
Let us suppose h be the total number of meals eaten in a home
- The total number of meals eaten in a restaurant, in a car or at home is given as 163. Hence,
![r + c + h = 171.....[A]](https://tex.z-dn.net/?f=r%20%2B%20c%20%2B%20h%20%3D%20171.....%5BA%5D)
- The total number meals eaten in a car or at home exceeds the number eaten in a restaurant by 11. Hence,
![c + h = r + 11.....[B]](https://tex.z-dn.net/?f=c%20%2B%20h%20%3D%20r%20%2B%2011.....%5BB%5D)
- Twenty more restaurant-purchased meals will be eaten in a restaurant than at home. Hence,
![r = h + 20.....[C]](https://tex.z-dn.net/?f=r%20%3D%20h%20%2B%2020.....%5BC%5D)
Substituting Equation [B] into [A],
![r + c + h = 171.....[A]](https://tex.z-dn.net/?f=r%20%2B%20c%20%2B%20h%20%3D%20171.....%5BA%5D)




Putting
in ![r = h + 20.....[C]](https://tex.z-dn.net/?f=r%20%3D%20h%20%2B%2020.....%5BC%5D)


Putting
and
in ![r + c + h = 171.....[A]](https://tex.z-dn.net/?f=r%20%2B%20c%20%2B%20h%20%3D%20171.....%5BA%5D)



Therefore,
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
