Explanation / Answer

The average tax rate equals taxes divided by income. It is 20%, 18%, and 15% on income of $1,000, $2,000, and $3,000, respectively. ======================================================================================================================== The tax is regressive because the tax rate declines as income increases. ======================================================================================================================== The marginal tax rate equals the change in income divided by the change in taxes. It is 20%, 15%, and 10% on the first $1,000, $2,000, and $3,000, respectively. ========================================================================================================================Income , Taxes Average Tax Rate Marginal Tax Rate ======================================================================================================================== 0 0 ======================================================================================================================== $1,000 $200 20% 20% ======================================================================================================================== $2,000 $350 18% 15% ======================================================================================================================== $3,000 $450 15% 10%
