Write a program named prices.c that repeatedly asks users to enter the price of an item until they enter zero. Prices less than zero will be ignored. The program will then print the number of items purchased, the subtotal of the prices, the sales tax charged (at a rate of 7.5%), and the grand total.

The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int quantity = 0;

double subtotal = 0;

double tax, grandTotal;

while (true) {

System.out.println("Enter a price: ");

double price = in.nextDouble();

if (price == 0) {

break;

} else if (price > 0) {

quantity += 1;

subtotal += price;

}

tax = subtotal * 0.075;

grandTotal = subtotal + tax;

System.out.println("Quantity: $" + quantity);

System.out.println("Subtotal: $" + subtotal);

System.out.println("Tax: $" + tax);

System.out.println("GrandTotal: $" + grandTotal);

}
