Answer:
The flat rental is 49$.
Step-by-step explanation:
We are given the following in the question:
The cost of renting van includes a rental fee and cost for distance traveled.
Let x be the flat rental fee and y be the cost per mile.
A van that is driven 107 miles costs $97.15
Thus, we can write the equation:
![97.15 = x + 107y](https://tex.z-dn.net/?f=97.15%20%3D%20x%20%2B%20107y)
A van that is driven 127 miles costs 106.15.
Thus, we can write the equation:
![106.15 = x + 127y](https://tex.z-dn.net/?f=106.15%20%3D%20x%20%2B%20127y)
Solving the two equations, we get,
![x + 127y - x - 107y = 106.15-97.15\\20y = 9\\y = 0.45\\x + 127(0.45) = 106.15\\x = 106.45-127(0.45) = 49](https://tex.z-dn.net/?f=x%20%2B%20127y%20-%20x%20-%20107y%20%3D%20106.15-97.15%5C%5C20y%20%3D%209%5C%5Cy%20%3D%200.45%5C%5Cx%20%2B%20127%280.45%29%20%3D%20106.15%5C%5Cx%20%20%3D%20106.45-127%280.45%29%20%3D%2049)
Thus, the flat rental is 49$.
