How to calculate or create the process calculating per hour rate

kilafan (11)
the condition given


if staff,code S
less than 8 hour-RM0.00
more than 8 hour-RM5.00 per entry
if not staff,code X
less than 8 hour-RM10.00 for first 3 hour
-RM5.00 per hour for next
between than 8 to 16 hour-RM10.00 for first 5 hour
-RM3.00 per hour for next
more than 16 hour-RM10.00

example
enter code-x
entry time-0830
exit time-1300
total hour-4 hour 30 minutes
total rate-rm17.50

	 printf("Total Hour: %d hours %d minutes ",h,m );


        	 if (code>='S')
		 {
		  if (total<480)

					  price=3.00;

				 }

			else if (total>960)
					  price=10.00;

				}


	 printf("Total Rate:RM %f",price);



}




the program can run
but the answer is wrong
whereas the process calculating per hour
I don't know how to do so
