one kind worth $0.17 per pound let this be x lbs.
\n" ); document.write( "with another worth $0.36 per pound. this will be 27-x lbs
\n" ); document.write( "27 pounds $0.26 per pound
\n" ); document.write( "..
\n" ); document.write( "0.17*x+0.36(27-x)=27*0.26
\n" ); document.write( "0.17x+9.72-0.36x= 7.02
\n" ); document.write( "-0.19x = -9.72+7.02
\n" ); document.write( "-0.19x=-2.70
\n" ); document.write( "x= -2.70/-0.19
\n" ); document.write( "= 14.2 lbs.
\n" ); document.write( "
