Answer:
c = 0.59x + 275
Explanation:
If x represents number of miles than $0.59 per mile fits in with that x. This would make it $0.59x.
As for the $275, its stated in text plus $275 so that would make it
$0.59 x + $275.
With this we can see its c = $0.59x + $275.
This was my way of thinking of how I looked at the text, I cant confirm if the way I explained it is correct.
