The cost of a bus excursion was $180. This amount was to have been shared equally by all those who said they wished to go.
\n" ); document.write( "---
\n" ); document.write( "Let that number of people be \"x\".
\n" ); document.write( "The average cost per person is 180/x dollars.
\n" ); document.write( "------------\r
\n" ); document.write( "\n" ); document.write( "However, 6 people failed to show up so that those who did go each had to pay $1.50 more.
\n" ); document.write( "Now the number of people is \"x-6\".
\n" ); document.write( "Now the average cost per person is 180/(x-6) dollars.
\n" ); document.write( "--------------\r
\n" ); document.write( "\n" ); document.write( "How many people actually went on the trip?
\n" ); document.write( "---
\n" ); document.write( "Solve: new average - old average = 1.50 dollars
