Essential Question: How does a progressive income tax system work and is it a good idea?

Tax code program:

Input: Using the command line input income in dollars. (This needs to be changed to cents inside the program.)



NTR = (taxDue) / (income) *100


Description: The program will round any tenths of a cent upward. "If" statements are not allowed. The program will use only algorithms to calculate taxes. It will use the following progressive tax table:

Income ($) Tax Rate Comments
        0 to 19,999.99  00 %

This part of income is never taxed

20,000 to 29,999,99 25 % Only income above $19,999.99 is taxed at 25%
30,000 +                    35 % Only Income above $29,999.99 is taxed at 35%. Note this is an additional 10% above the 25% tax that kicks in at $29,999.99.


Essential Question: Do we live in a binary world?
