2.85X+2.60(90-X)=2.75*90
\n" ); document.write( "2.85X+234-2.60X=247.5
\n" ); document.write( ".25X=247.5-234
\n" ); document.write( ".25X=13.5
\n" ); document.write( "X=13.5/.25
\n" ); document.write( "X=54 LB. OF $2.85 TEA.
\n" ); document.write( "90-54=36 LB. OF $2.60 TEA.
\n" ); document.write( "PROOF:
\n" ); document.write( "2.85*54+2.60*36=2.75*90
\n" ); document.write( "153.9+93.6=247.5
\n" ); document.write( "247.5=247.5
