/** 
 * Coffee discounts :
 * The Java Coffee Outlet sells only one type of coffee beans harvested 
 * exclusively in the remote area of Irian Jaya.  The company sells the 
 * coffee in 2-lb bags only,
 * and the price of a single 2-lb bag is $5.50.  Discounts are given 
 * to volume buyers.  The discount is based on the following table:
 
 * Order Volume	Discount
 * more than 25 bags	5% of the total price
 * more than 50 bags	10% of the total price
 * more than 100 bags	15% of the total price
 * more than 150 bags	20% of the total price
 * more than 200 bags	25% of the total price
 * more than 300 bags	30% of the total price

 * Write a program that accepts the number of bags ordered 
 * and prints out the total cost of the order.
