p=h+40
\n" ); document.write( ".75p+1.35h=292.50
\n" ); document.write( ".75(h+40)+1.35h=292.50
\n" ); document.write( ".75h+30+1.35h=292.50
\n" ); document.write( "2.1h=292.50-30
\n" ); document.write( "2.1h=262.5
\n" ); document.write( "h=262.5/2.1125
\n" ); document.write( "h=125 hamburgers were sold.
\n" ); document.write( "p=125+40=165 pieces of pizza were sold.
\n" ); document.write( "Proof:
\n" ); document.write( ".75*165+1.35*125=292.50
\n" ); document.write( "123.75+168.75=292.50
