\n" ); document.write( "According to the IRS (Internal Revenue Service, www.irs.gov), a single taxpayer with a taxable income over $319,100 in 2004 paid $92,592.50 plus 35% of the amount over $319,100. If Glen paid $255,836 in federal income tax for 2004, then what was his taxable income for 2004?
\n" ); document.write( "-----
\n" ); document.write( "let T = tax glen paid.
\n" ); document.write( "let I = glen's taxable income
\n" ); document.write( "general formula is T = $92592.5 + (.35*(I - $319100)
\n" ); document.write( "this becomes
\n" ); document.write( "$255836 = $92592.5 + (.35*(I - $319100)
\n" ); document.write( "subtracting 92592.5 from both side of the equation and it becomes
\n" ); document.write( "$163243.5 = (.35*(I - $319100)
\n" ); document.write( "removing parentheses from right side of equation and it becomes
\n" ); document.write( "$163243.5 = .35*I - .35*$319100
\n" ); document.write( "multiplying .35*$319100 and adding it to both sides of the equation and it becomes
\n" ); document.write( "$163243.5 + $111685 = .35*I
\n" ); document.write( "doing the addition on the left side of the equation and dividing both sides of the equation by .35 and it becomes
\n" ); document.write( "$274928.5/.35 = I
\n" ); document.write( "solving for I and the equation becomes
\n" ); document.write( "$785510 = I
\n" ); document.write( "-----
\n" ); document.write( "answer looks like Glen's income is $785510
\n" ); document.write( "to prove correct, calculate Glen's taxes.
\n" ); document.write( "formula again is T = 92592.5 + (.35*(I - $319100)
\n" ); document.write( "this becomes
\n" ); document.write( "T = 92592.5 + (.35*($785510 - $319100)
\n" ); document.write( "this becomes
\n" ); document.write( "T = 92592.5 + (.35*$466410)
\n" ); document.write( "this becomes
\n" ); document.write( "T = 92592.5 + $163243.5
\n" ); document.write( "which becomes
\n" ); document.write( "T = $255836
\n" ); document.write( "-----
\n" ); document.write( "answer is confirmed.
\n" ); document.write( "Glen's Taxable Income is $785,510.00\r
