# amount of tax for a single taxpayer with taxable income

1) Consider the following nine integers:
-4, -3, -2, -1, 0, 1, 2, 3, 4

Which of these integers has an absolute value greater
than 1?

2) Evaluate each expression using a=-1, b= 2, and c=-3.
(a-c)(a+c)

3) Married filing jointly. The value of the expression
8440+0.25(x-61,300)
is the 2006 federal income tax for a married couple filing
jointly with a taxable income of x dollars, where x is over
\$61,300 but not over \$123,700 (Internal Revenue
Service, www.irs.gov).
a) Simplify the expression.
b) Use the expression to find the amount of tax
for a couple with a taxable income of \$80,000.
c) Use the accompanying graph to estimate the 2006
federal income tax for a couple with a taxable income
of \$200,000
d) Use the accompanying graph to estimate the taxable
income for a couple who paid \$80,000 in federal
income tax.

4) Marriage penalty eliminated. The value of the expression
4220+0.25(x-30,650)
is the 2006 federal income tax for a single taxpayer with
taxable income of x dollars, where x is over \$30,650 but
not over \$74,200.
a) Simplify the expression.
b) Find the amount of tax for a single taxpayer with
taxable income of \$40,000.
c) Who pays more, a married couple with a joint taxable
income of \$80,000 or two single taxpayers with
taxable incomes of \$40,000 each? See Exercise 123.
