# How to solve this problem

We value the Simple Design so if possible try to apply it.  A design is simple

when:

1. pass all tests

2. contains no duplication

3. express the intent (good names)

4. is minimal

This problem requires some kind of input. You don't have to set up a user 

interface to do this, just put the input as hard coded data within unit tests. 

You should provide sufficient evidence that your solution is complete by, as a 

minimum, indicating that it works correctly against the supplied test data 

(see section Examples below).  Your should also provide an automated test 

suite that verifies your solution against these test data.

# Problem: Sales Taxes

Basic sales tax is applicable at a rate of 10% on all goods, except books, 

food, and medical products that are exempt. Import duty is an additional sales 

tax applicable on all imported goods at a rate of 5%, with no exemptions.

When I purchase items I receive a receipt which lists the name of all the 

items and their price (including tax), finishing with the total cost of the 

items, and the total amounts of sales taxes paid. The rounding rules for sales 

tax are that for a tax rate of n%, a shelf price of p contains (np/100 rounded 

up to the nearest 0.05) amount of sales tax.

Write an application that prints out the receipt details for these shopping 

baskets...
