A car rental company charges for mileage as follows: x dollars per mile for the first n miles and x + 1 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 the correct choice from the following choices
A) d( x + 1) – n
B) xn + d
C) xn + d( x + 1)
D) x( n + d) – d
E) (x + 1)( d – n)
Cost of mileage for the first n miles = nx   Cost of mileage for the next d-n miles = (d-n)(x+1)   Total cost   = nx + (d-n)(x+1)   = nx + dx+d-nx-n   = dx+d-n   = d(x+1) - n   d( x + 1) – nnswer d( x + 1) – n
