- the price for all those items (tax not included)

- the prices of all items requested, after applying the sales tax (6%)
- the average price after tax
Hint: You should use two arrays of real numbers in order to store the prices of all items before and after tax
Example of Running:
Input the number of office supply items needed: 3
Input the prices (before tax) for all 3 items:
16.99
100.25
