THIS IS THE QUESTION.
1 The user would enter how many minutes he/she would like to park in the parking lot.
2 The program would output the parking cost.
3  The rate charge by the parking lot is as follows
First 3 hours  USD4/Hour
Hours 4 to 8  USD3/Hour
Hours 9 onwards  USD2/Hour
I ALSO NEED TO CONSIDER TO:
1. Parking for 120 minutes is considered 2 hours and therefore would cost USD 8 (2 hour x USD 4)  DONE
2. Parking for 121 minutes is considered 3 hours and therefore would cost USD 12 (3 hour x USD 4)  DONE.
This is i am lack ..
3. Parking for 190 minutes is considered 4 hours and therefore would cost USD15 (3 hours x USD 4 + 1 hour x USD 3)
4. Parking for 490 minutes is considered 9 hours and therefore would cost USD 29 (3 hours x USD4 + 5 hours x USD 3 + 1 hour x USD 2)
SO ,, THIS IS WHAT I AM TRYING TO DO,,BUT FAILED..
