Here is the code given: public class Billing { final static double TAX = 0.08; public static void main(String[] args) { final double HIGHPRICE = 24.99; final double MEDPRICE = 17.50; final double LOPRICE = 10.00; final int QUAN1 = 4; final int QUAN2 = 6; double bill; bill = computeBill(HIGHPRICE); System.out.println("The total for a photobook that costs $" + HIGHPRICE + " is $" + bill); bill = computeBill(MEDPRICE, QUAN1); System.out.println("The total for " + QUAN1 + " photobooks that cost $" + MEDPRICE + " is $" + bill); bill = computeBill(LOPRICE, QUAN2, 20.00); System.out.println("The total for " + QUAN2 + " photobooks that cost $" + LOPRICE + " with a $20 coupon is $" + bill); } public static double computeBill(double amt) { // Write your code here } public static double computeBill(double amt, int quantity) { // Write your code here } public static double computeBill(double amt, int quantity, double coupon) { // Write your code here } } Here is what they are asking for me to do: Create a class named Billing that includes three overlaoded computeBill(0 methods for a photo book store. When computeBill() recieves a single parameter, it represents the price of one book ordered.  Add 8% tax, and return the total due. When computeBill() recieves two parameters, they represent the price of a photo book and the quantity ordered.  Multiply the two values, add 8% tax, and return the total due When computeBill() recieves three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value.  Multiply the quantity price, redue the result by the coupon vlaue, and then add 8% tax and return the total due.

I keep coming up with the wrong answer, please help:

Here is the code given:

public class Billing {
final static double TAX = 0.08;
public static void main(String[] args) {
final double HIGHPRICE = 24.99;
final double MEDPRICE = 17.50;
final double LOPRICE = 10.00;
final int QUAN1 = 4;
final int QUAN2 = 6;
double bill;
bill = computeBill(HIGHPRICE);
System.out.println("The total for a photobook that costs $" +
HIGHPRICE + " is $" + bill);
bill = computeBill(MEDPRICE, QUAN1);
System.out.println("The total for " + QUAN1 +
" photobooks that cost $" +
MEDPRICE + " is $" + bill);
bill = computeBill(LOPRICE, QUAN2, 20.00);
System.out.println("The total for " + QUAN2 +
" photobooks that cost $" +
LOPRICE + " with a $20 coupon is $" + bill);
}

public static double computeBill(double amt) {
// Write your code here
}

public static double computeBill(double amt, int quantity) {
// Write your code here
}
public static double computeBill(double amt, int quantity, double coupon) {
// Write your code here
}
}

Here is what they are asking for me to do:

Create a class named Billing that includes three overlaoded computeBill(0 methods for a photo book store.

When computeBill() recieves a single parameter, it represents the price of one book ordered.  Add 8% tax, and return the total due.

When computeBill() recieves two parameters, they represent the price of a photo book and the quantity ordered.  Multiply the two values, add 8% tax, and return the total due

When computeBill() recieves three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value.  Multiply the quantity price, redue the result by the coupon vlaue, and then add 8% tax and return the total due.
