Question 526618


If it's 20 cents per one-tenth of a mile, then it's 200 cents per mile (multiply both quantities by 10)


So it's really $2 per mile.


So if you drive x miles, then the variable cost is 2x dollars.


Add this to the fixed cost to get 2x+2


So the total fare for driving x miles is 2x+2 dollars.


This means that the cost equation is 


c = 2x+2


Now if you drive 10 miles, then x = 10 and


c = 2x+2


c = 2(10)+2


c = 20+2


c = 22


which means that a 10 mile journey will cost 22 dollars.
