Answer:
![y = 0.42x+55](https://tex.z-dn.net/?f=y%20%3D%200.42x%2B55)
Step-by-step explanation:
Given
Let:
![x \to miles](https://tex.z-dn.net/?f=x%20%5Cto%20miles)
![y \to amount](https://tex.z-dn.net/?f=y%20%5Cto%20amount)

The equation
First, calculate the slope (m)
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m = \frac{142.78 - 112.96}{209 - 138}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B142.78%20-%20112.96%7D%7B209%20-%20138%7D)
![m = \frac{29.82}{71}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B29.82%7D%7B71%7D)
![m = 0.42](https://tex.z-dn.net/?f=m%20%3D%200.42)
The equation is calculated using:
![y = m(x - x_1) + y_1](https://tex.z-dn.net/?f=y%20%3D%20m%28x%20-%20x_1%29%20%2B%20y_1)
So, we have:
![y = 0.42(x - 138) + 112.96](https://tex.z-dn.net/?f=y%20%3D%200.42%28x%20-%20138%29%20%2B%20112.96)
![y = 0.42x - 57.96 + 112.96](https://tex.z-dn.net/?f=y%20%3D%200.42x%20-%2057.96%20%2B%20112.96)
![y = 0.42x+55](https://tex.z-dn.net/?f=y%20%3D%200.42x%2B55)

Answer:1190
Step-by-step explanation:
Whit the car: 2x70=140
Whit the jet:3x350=1050
140+1050=1190
The shift from the agriculture economy to consumer markets led to the free enterprise system.
