Average corporate tax rates Using the corporate tax rate schedule given here $i,$ perform the following:

a$.$ Calculate the tax liability, after$-$tax earnings, and average tax rates for the following levels of corporate earnings

before taxes: $$10,400$;$$81,900$;$$302,000$;$$499,000$;; $$1\mathrm{.}9$ million; $$9\mathrm{.}4$ million; and $$19\mathrm{.}6$ 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?

a$.$ Find the marginal tax rate for the following levels of corporate earnings before taxes: $$10,400$;$$81,900$;$$302,000$;

$$499,000$;$$1,900,000$;$$9\mathrm{.}4$ million; and $$19\mathrm{.}6$ million.

The tax liability for earnings before taxes of $$10,400$ is $$1,560.($Round to the nearest dollar.$)$

The after$-$tax earnings on $$10,400$ are $$8840.($Round to the nearest dollar.$)$

The average tax rate for the $$10,400$ in pretax earnings is $15\%.($Round to one decimal place.$)$

The tax liability for earnings before taxes of $$81,900$ is $$16,096.($Round to the nearest dollar.$)$

The after$-$tax earnings on $$81,900$ are $$65804.($Round to the nearest dollar.$)$

The average tax rate for the $$81,900$ in pretax earnings is $19\mathrm{.}7\%.($Round to one decimal place.$)$

The tax liability for earnings before taxes of $$302,000$ is $$.($Round to the nearest dollar.$)$Please
