1.85X+1.15(25-X)=1.50*25
\n" ); document.write( "1.85X+28.75-1.15X=37.50
\n" ); document.write( ".70X=37.50-28.75
\n" ); document.write( ".70X=8.75
\n" ); document.write( "X=8.75/.70
\n" ); document.write( "X=12.50 POUNDS OF MIXED NUTS ARE USED.
\n" ); document.write( "25-12.50=12.50 POUNDS OF OATS ARE USED.
\n" ); document.write( "PROOF:
\n" ); document.write( "1.85*12.5+1.15*12.5=1.50*25
\n" ); document.write( "23.125+14.375=37.50
