<PRE><B>Question 506686</B>
 Write the equation for this situation: the cost, c, in dollars of a car rental is equal to 10 dollars plus 1/2 the miles driven, m.
-----
c(x) = 10 + (1/2)x
------------------------ 
Then graph the equation and use the graph to determine the cost of the car rental if the number of miles driven is 12. 
_____
{{{graph(400,400,-10,10,-10,10,(1/2)x+10)}}}
----
c(12) = 10 + (1/2)12 = $16
