Kate calculates that she owes _________ in income taxes for 2015. Kate then calculates that her average tax rate is ____, based on the annual income level and the amount of taxes she owes for 2015.

The maximum amount that Kate is willing to pay to learn this strategy and reduce her taxable income by $4,000 is ________.
