Suppose that in 2015, Congress passed and the president signed a new simple income tax with a flat rate of 25 percent on all income greater than $25,000 (no tax on the first $25,000). Assume that the tax is imposed on every individual separately. For each of the following total income levels, calculate taxes due and compute the average tax rate. If income is $35,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) If income is $45,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) If income is $55,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) If income is $65,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) If income is $80,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) If income is $90,000, total taxes due are $ and the average tax rate is percent. (Round your responses to two decimal places.) Now plot the average tax rate on a graph with income along the horizontal axis. Using the three-point curved line drawing tool, plot the general shape of the relationship between income and the average tax rate. Label your line 'Average tax rate.' The tax is _______ because its burden, expressed as a percentage of income, _______ as income increases
