## Tax Brackets

### January 26, 2021

My W-2 form came in the mail a few days ago, so a task about taxes is appropriate. Given the following tax brackets:

````income cap    tax rate`
`  \$ 10,000        0%`
`  \$ 30,000       10%`
`  \$100,000       25%`
`    more         40%````

Calculate the amount of tax given an amount of income. The tax brackets work like this: If your income is less than \$10,000, your tax is \$0. If your income is between \$10,000 and \$30,000, your tax is 10% of your income in excess of \$10,000. If your income is between \$30,000 and \$100,000, your tax is 10% of the \$20,000 of income between \$10,000 and \$30,000 (or \$2,000) plus 25% of your income over \$30,000. If your income is over \$100,000, your tax is 10% of the \$20,000 of income between \$10,000 and \$30,000 (or \$2,000), plus 25% of your income between \$30,000 and \$100,000 (or \$17,500), plus 40% of your income over \$100,000 (ouch!).

For example, if your income is \$123,456, your tax is \$2,000 plus \$17,500 plus 40% of \$23,456 (or \$9,382.40), a total tax of \$28,882.40, or 23.4% of your income.

Your task is to write a program that calculates the amount of tax due for a given amount of income. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
