Cost per mile = ![\frac{cost}{number of miles}](https://tex.z-dn.net/?f=%5Cfrac%7Bcost%7D%7Bnumber%20of%20miles%7D)
![= \frac{485}{500}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B485%7D%7B500%7D)
= 0.97
Now,
c - cost for gasoline and maintenance and
m - number of miles traveled
Hence, the required expression is c = 0.97m.
Good morning
(-6m^7 + 20m^6) / 2m^4
= (-6m^3 + 20m^2) / 2
Now just divide them
-3m^3 + 10m^2
I hope that's help !
