Assignment

A convenience store sells T-shirt, potato chips, and Coke. The list prices are: $18.95 for T-shirt,
$1.79 for a bag of potato chips, and $2.99 for a 12-pack Coke ($1.20 deposit as well). All merchandise
except Coke is on sale with 15% off the list price. T-shirt is also charged a 6% Michigan sales tax.
A customer shops at the store to buy these items. Write a Java program to simulate the shopping
process — interact with the custom and prints a receipt.

Code

import java.util.Scanner;

public class a {
