NOTE: you will be uploading this file through this Canvas page. Do not post this to your website.

The Discount Store offers discounts when you purchase multiple items of any item. Here is their discount schedule:

Number of Items	Discount Rate
0 - 5	0%
6 - 20	10%
21 - 50	15%
51 - 100	20%
over 100	25%

User Interface Specifications

The user must input the normal cost of the item, and the # of items purchased.

As output, the program should redisplay the user input and then the discount rate, the original cost, the amount saved, and the total discounted cost. See Sample Run at bottom of page.

Your output should look the same as the sample output below:

use of bold and underline

numbers formatted to 2 decimal places

use of blank lines

units

(2 BONUS POINTS) If the user enters a number of items less than zero, or an item price less than zero, the program should display a message saying so. It should NOT calculate and display any information for this situation. It is typical to test for this invalid input condition as the first test in a series of tests.

Documentation and Other Style Issues

Use descriptive variable names.

Make sure your code is organized. Input, calculations, and output sections should be distinct

Your html must be correct, as we've learned. Include your name in an html comment at the top of the file.

Sample Run
