Part 1
If you have not already had a paying job, when you get your first paycheck, you will notice various taxes are
deducted. Those required include social security and federal income tax and may include state taxes (Virginia, Maryland
& DC have state taxes, however, Florida, Texas, and Nevada do not have state income taxes). Federal income taxes rates
are different for single, married, head of household or married filing separately. The money withheld each pay period is
an estimate of what you will owe for the year. At the end of the year, you will receive a W-2 that is used to file your
taxes with the IRS. This together with other income and deduction will be used to calculate the exact amount of taxes
you will the IRS. For this assignment, we are simplifying the process to allow the user to enter the dollar amount that
will be taxed and the program should return the tax.
Create a program that calculates the 2010 federal income taxes for either a single filer or a married filer.

For this program, you MUST use both an IF statement and a SELECT CASE statement (suggestions, use the If statement to
determine if the user is married or single and a Case statement to determine the tax).
