wage

/*4. An employee receives the regular pay rate for the first 30 hours and he is paid 1½ 

times the normal rate for each hour over the 30 hours. Write a program (save it as 

BonusWage) that prompts the user for the regular pay rate and the hours worked and 

then it will calculate and display on screen the employee’s wage based on that 

information and the criteria mentioned above. For example, if 42 is entered for hours and 

6.00 for rate, then the amount to display should be $288.00.

public class BonusWage  {

	public static void main(String[] args) {
		String wage;
		String hours
		Scanner input = new Scanner(System.in);
		
		System.out.println("Enter your wage");
		wage = input.nextLine();
		System.out.println("Enter the amount of hours you worked")
		hours = input.nextLine();

		if (hours <= 30){
			System.out.println("Your total salary is:" + wage * hours);
		} 
		else if (hours > 30) {
			System.out.println("Your total salary is" + wage * 1.5 *hours) 
		}
	} 
}

The second if should be:
System.out.println("Your total salary is" + wage * (30 + 1.5 *(hours-30) ) );
since the 1.5 is applied to each hour in addition to the 30 hours.
