a) When computeBill() recieves single parameter, it represents price of one photo book ordered. Add 8% tax and return the total due.
b) When computeBill() recieves two parameters, they represent price of a photo book and the quantity ordered. Multiply the two values, add 8% tax, and return the total due.
c) When computeBill() recieves three parameters, they represent the price of a photo book, quantity ordered, and the coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and return the total due.
d) Write a main() method which test all three overloaded methods.
