import java.util.Scanner;

public class NetIncomeCalculator {

 /**
  * This program calculates gross pay
  * and net pay given deductions in 
  * Social Security, medicare and a bus
  * pass. This is the equivalent of

Here is the output from the program

Enter the number of hours worked
45
Enter your rate per hour
25
Your gross income is 1187.5
Your Social Security deduction is 106.875
Your Medicare deduction is 35.625
Your Bus pass deduction is 25
Your net pay is 1020.0
