Modify code below; 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

}

}

Remember: double total = amount + amount * taxrate;

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

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

can someone please explain this to me when you write the answer? please and thank you.
just do an sample problem instead of the actual problem so i understand it more better.
