> solve this simple exercise, you can choose whatever programming language you prefer

This problem requires some kind of input. You are free to implement any
mechanism for feeding input into your solution (for example, using hard coded
data within a unit test). You should provide sufficient evidence that your
solution is complete by, as a minimum, indicating that it works correctly
against the supplied test data.

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.
