Object-Oriented Order Calculator

In this assignment we will be creating an object-oriented order total price calculator. Your branch already has a failing test, your job is to make it pass. You will not need to make changes to the test file, but feel free to add more tests to the test file if it can help you in developing the code. Create a new file named 'order.rb' and put your code in there.

To do this, you will need to make 3 classes.

1. Product

   The product class needs to have name and price accessors and a constructor to allow you to set those values. If you aren't sure how to do this, refer to the slides on the flexible initializer

Assignment for Ruby Basics

Implement the calculate_total method so that the tests pass. The method should accept an order represented as an Array of Hashes and calculate the total cost of the order. Each Hash should represent a line item of the order with a key for the quantity and a key for the unit price of the item. After calculating the total of the order and additional tax rate of 5% should be added. The return value should be a string, the total formatted as a price with 2 decimal points and a dollar sign, such as $1.99.

Hints

• Don't hard code the tax rate as a magic number. If you aren't sure how to avoid that, refer to this slide on when to use constants

• Make sure you know how to create an Array of Hashes first. If you are not sure, re-read the slides on Arrays and [Hashes](http://pjb3.github.io/back-end-web-
