Question 932709
(a) The cost expression is <font color="red">5000 + 50x</font> because you take the initial cost of $5000 and you add on an additional 50x dollars. The 50x represents the cost for driving x miles.



----------------------------------------------------------------------------



(b) Take cost expression (5000 + 50x) from part (a) and replace every x with 60 and evaluate


5000 + 50x
5000 + 50(60)
5000 + 3000
8000


So the total cost for driving 60 miles is <font color="red">$8,000</font>
