A car rental company charges for mileage as follows: 6 dollars per mile for the first n miles and 7 dollars per mile for each mile over n miles. How much will the mileage charge be, in dollars, for a journey of d miles, where d > n ?
Pick one:	A) 7d-n	B) 6*7d-n	C) 11d-n	D) 13d-n	E) 15d-n
Total Distance in miles = d   Millage Charge = 6n + (d-n) 7   6n --&gt; For the first n Miles   (d-n)7--&gt; Total no of miles after traveling the first n miles is d-n and the rate after n miles is 7 .   If we solve the equation , We will get 7d-n   7d-nnswer : 7d-n
