Instructions

Your company is selling a variety of widgets.
The user has found the widget s/he wants and now wants to buy it.  For testing purposes,
assume the user wants to buy the green widget and that it costs 100.

Create a new document called widget.html.

    * Write a JS function to
          o find out the name and the price of the widget the user wants to buy.
          o calculate the tax (based on 8%) and the final price.
    * Create another JS function to
          o tell the user (on the page) the name of the widget ordered, how much it costs,
          the tax and the final price.

Call the functions so that your output might look like this:

You want to buy the green widget.
It costs $100.
The tax is $8.
The total amount is $ 108.
