A car rental company charges for mileage as follows: 10 dollars per mile for the first n miles and 11 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 ? Choose one.
A) 7d-n
B) 5d-n
C) 3*11d-n
D) 11d-n
E) 4d-n
Total Distance in miles = d   Millage Charge = 10n + (d-n) 11   10n --&gt; For the first n Miles   (d-n)11--&gt; Total no of miles after traveling the first n miles is d-n and the rate after n miles is 11 .   If we solve the equation , We will get 11d-n   Answer : 11d-n
