"The price of compact fluorescent light bulbs fell because of improvements in
production technology. As a result, the demand for incandescent light bulbs decreased.
This caused the price of incandescent light bulbs to fall; as the price of incandescent
light bulbs fell the demand for incandescent light bulbs decreased even further."
Evaluate this statement.
A) The statement is false. A decrease in the price of compact fluorescent light bulbs
would decrease the demand for incandescent light bulbs, but a decrease in the price of
incandescent light bulbs would not cause the demand for incandescent light bulbs to
decrease.
B) The statement is false because the demand for incandescent light bulbs would
increase as the price of compact fluorescent light bulbs fell.
C) The statement is false because compact fluorescent light bulbs producers would not
reduce their prices as a result of improvements in technology; doing so would reduce
their profits.
D) The statement is false because it confuses the law of demand with the law of supply.

Last year, Anthony Millanti earned exactly $30,000 of taxable income. Assume that the
income tax system used to determine Anthony's tax liability is progressive. The table
below lists the tax brackets and the marginal tax rates that apply to each bracket.

pay for each tax bracket, and the total tax he owes the government. (Assume that there
are no allowable tax deductions, tax credits, personal exemptions, or any other
deductions that Anthony can use to reduce his tax liability).
b. Determine Anthony's average tax rate.
