I can't seem to get this cost of a moble service program to work.

For future reference, when you copy/paste code to the forum, choose the "paste as text option".

30 if (unit <=10)
31
32 charges = 9.95
33 else
34 (unit > 10)
35
36 charges = (unit * 2) + 9.95;

Two things,
1. There is no condition associated with else, so get rid of the (unit > 10)
2. Always use braces to make your intention explicit.

 if (unit <=10) {
       charges = 9.95
 } else {
       charges = (unit * 2) + 9.95;
 }
