Using the individual tax rate schedule $,$ perform the following:

a$.$ Calculate the tax liability, after$-$tax earnings, and average tax rates for the following levels of partnership earnings before taxes: $$12,300$;$$77,100$; $$312,000$; $$497,000$;$$1\mathrm{.}1$

million; $$1\mathrm{.}6$ million; and $$2\mathrm{.}1$ million.

b$.$ Plot the average tax rates $($measured on the $y-$axis$)$ against the pretax income levels $($measured on the x$-$axis$).$ What generalization can be made concerning the relationship

between these variables?
