End-To-End-Example: Fudgebonia Taxes

The country of “Fudgebonia” determines your tax rate from the number of dependents:

0 is 30%
1 is 25%
2 is 18%
3 or more is 10%

Write a program to prompt for number of dependents (0-3) and annual income.

It should then calculate your tax rate and tax bill. Format numbers properly! Handle bad input!
