Price of Adults' Supper = $6.80
\n" ); document.write( "Price of Children's supper = 6.80/2 = $3.40
\n" ); document.write( "Total Amount Collected = $2444.60\r
\n" ); document.write( "\n" ); document.write( "Let
\n" ); document.write( "No. Adults were = x
\n" ); document.write( "No. Children were = 387-x\r
\n" ); document.write( "\n" ); document.write( "(No. Children)*(price of children's supper)+(No. Adults)*(price of Adult's supper) = Total Amount Collected
\n" ); document.write( "(387-x)(3.40)+(x)(6.80)=2444.60
\n" ); document.write( "1315.80-3.40x+6.80x=2444.60
\n" ); document.write( "3.40x=2444.60-1315.80
\n" ); document.write( "3.40x=1128.80
\n" ); document.write( "x=1128.80/3.40
\n" ); document.write( "x=332\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "No. Adults were = x = 332
\n" ); document.write( "No. Children were = 387-x = 387-332=55\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "No. Adults *6.80+ No. Children = Total Collection
\n" ); document.write( "332*6.80+55*3.40=2444.60
\n" ); document.write( "2257.60+187=2444.60
