Taxes paid for a given income level

Suppose that Eric is preparing to file his taxes. He is single and currently lives in Chicago. Eric earned $$110,000$ in taxable income in $2022.$ He reviews the following table, which shows the IRS tax rates for a single taxpayer in $2022.$

$\backslash$table$[[$On Annual Taxable Income...,$\backslash$table$[[$The Tax Rate Is$...],[($Percent$)]]],[$Up to $$10,275,10\mathrm{.}0],[$From $$10,275$ to $$41,775,12\mathrm{.}0],[$From $$41,775$ to $$89,075,22\mathrm{.}0],[$From $$89,075$ to $$170,050,24\mathrm{.}0],[$From $$170,050$ to $$215,950,32\mathrm{.}0],[$From $$215,950$ to $$539,900,35\mathrm{.}0],[$Over $$539,900,37\mathrm{.}0]]$

Based on the IRS table, Eric calculates that his marginal tax rate is $q,$ when his annual taxable income is $$110,000.$

Eric calculates that he owes $\_$ in income taxes for $2022.$

Eric then calculates that his average tax rate is $q,,$ based on the annual income level and the amount of taxes he owes for $2022.$

After figuring out what he owes in taxes in $2022,$ Eric decides to ask an accountant for tax advice. The accountant claims that he has found a legal way to shelter $$2,000$ of taxable income from the federal government.

The maximum amount that Eric is willing to pay to learn this strategy and reduce his taxable income by $$2,000$ is $.($Hint: Sheltering some income means finding a legal way to avoid being charged income tax on that income. For example, someone who has $$50,000$ in taxable income and shelters $$10,000$ pays income tax on only $$40,000.)$
