## Objective

Given a collection of prices of some items, output a table showing each price, the discount offered, and the price after the discount.

Easy

## Description

You are given the following array, modeling the pricing of a couple of items in a shopping store:

``````<?php

\$items = [[50, 30], [85, 10], [300, 15], [20, 5]];``````

Each item of this array is an array itself, consisting of two elements: the first is the actual price of the item (in \$) in the store (without a discount) and the second is its discount, given as a percentage value.

For instance, `[50, 30]` means that the actual price of the item is \$50 while the discount is 30%. If we compute the price after applying the discount, it turns out to be \$35.

In this exercise, your job is to output a table (in the terminal) using this array, showing each item's actual price, its discount, and price after discount.

Here are a couple of things to abide by:

• Each column should be of length 20, with a space in between, and the text within it should be left-aligned.
• The headings of the table should be 'Price', 'Discount' and 'Price after discount', respectively.
• After the table's header row, leave a blank line.
• Furthermore, wherever prices are output, they should be to 2 decimal places and begin with the `\$` sign. For instance, if the price is `30`, it should be output as `\$30.00`; if the price is `50.789`, it should be output as `\$50.79`; and so on and so forth.
• The discount should be output with a `%` sign at its end. For instance, if the discount is `20`, the output should be `20%`.

Shown below is the required output for the `\$items` array shown above:

Price Discount Price after discount \$50.00 30% \$35.00 \$85.00 10% \$76.50 \$300.00 15% \$255.00 \$20.00 5% \$19.00
