preteens x------------------- $2
\n" ); document.write( "teens = 3x/4-------------------$3\r
\n" ); document.write( "\n" ); document.write( "Adults = total - (preteens + teens)\r
\n" ); document.write( "\n" ); document.write( "Adults = 570-((3x/4)+x).
\n" ); document.write( "= 570-(7x/4)..........................$5\r
\n" ); document.write( "\n" ); document.write( "Total receipts\r
\n" ); document.write( "\n" ); document.write( "2x+3*(3x/4) +5(570-(7x/4))=1950\r
\n" ); document.write( "\n" ); document.write( "2x+9x/4 + 2850-35x/4 = 1950\r
\n" ); document.write( "\n" ); document.write( "multiply equation by 4\r
\n" ); document.write( "\n" ); document.write( "8x+9x+4*2850-35x=4*1950
\n" ); document.write( "-18x= -3600\r
\n" ); document.write( "\n" ); document.write( "x= 200 pre teens\r
\n" ); document.write( "\n" ); document.write( "Teens = 3/4 * 200 = 150\r
