-------------
Subtract the daily charge from the overall charge.
The difference is the charge for mileage.
-------
Always get unlimited mileage.

We rented a Lincoln in BWI in drove it 1100 miles in 5 days. The guy at the place where we returned assumed it was a mistake and put 100 miles on the paperwork. Not that it affected the overall charge.

As Alan just explained it to you in his post, the problem can be solved in one line : 

    miles = %28158-35%29%2F0.30.

It is how any similar problem should be solved: in one line.

And you should clearly understand, why this method works.
