Let x=amount spent to gain a revenue of $180,000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We simply have this relationship\r
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "\r\n" );
document.write( "money spent on advertising     unknown amount of money spent on advertising \r\n" );
document.write( "-------------------------- = -----------------------------------------------\r\n" );
document.write( "        Revenue                                 New Revenue\r\n" );
document.write( "\r\n" );
document.write( "
\r
\n" ); document.write( "\n" ); document.write( "So that means we have the equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2000%2F120000=x%2F180000\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"180000%282000%2F120000%29=x\" Multiply both sides by 180,000\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"180000%281%2F60%29=x\" Reduce the fraction in the parenthesis\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"180000%2F60=x\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3000=x\" Reduce\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So when $3,000 dollars is spent on advertising, the revenue is $180,000
\n" ); document.write( "
\n" );
