In 2008, U.S. companies spent a total of
\n" ); document.write( "$118.2 billion on newspaper, television, and magazine
\n" ); document.write( "ads.
\n" ); document.write( "The total amount spent on television ads was
\n" ); document.write( "$10.8 billion more than the amount spent on newspaper
\n" ); document.write( "and magazine ads together.
\n" ); document.write( "The amount spent on magazine ads was $3.5 billion
\n" ); document.write( "more than the amount spent on newspaper ads.
\n" ); document.write( "--------
\n" ); document.write( "Equations:
\n" ); document.write( "n + t + m = 118.2
\n" ); document.write( "t = n + m + 10.8
\n" ); document.write( "m = n + 3.5
\n" ); document.write( "------
\n" ); document.write( "Note:: t = n + n+3.5 + 10.8 = 2n + 14.3
\n" ); document.write( "----
\n" ); document.write( "Substitute for t and m and solve for \"n\"::
\n" ); document.write( "n + 2n+14.3 + n + 3.5 = 118.2
\n" ); document.write( "-----
\n" ); document.write( "4n + 17.8 = 118.2
\n" ); document.write( "4n = 100.4\r
\n" ); document.write( "\n" ); document.write( "How much was spent on each form
\n" ); document.write( "of advertising?
\n" ); document.write( "-----\r
\n" ); document.write( "\n" ); document.write( "n = 25.1B (amt spent on newspaper ads)
\n" ); document.write( "Solve for t = 2n+14.3
\n" ); document.write( "Solve for m = n+3.5
