x=pounds of cashews
\n" ); document.write( "4x=revenue of cashew.
\n" ); document.write( "profit will be $105 (70 pounds of peanuts @$1.50 lb)
\n" ); document.write( "4x+105=(70+x)(3.50)
\n" ); document.write( "4x+105=245+3.50x
\n" ); document.write( "0.5x=140
\n" ); document.write( "x=280 pounds of cashews.
\n" ); document.write( "check
\n" ); document.write( "350 pounds @3.50 per pound is $1225.
\n" ); document.write( "280 pounds of cashews are $1120
\n" ); document.write( "70 pounds of peanuts are $105
\n" ); document.write( "That adds to $1225.
\n" ); document.write( "This makes sense, because the average price is going to be very close to what cashews sell for, so one would expect more cashews in the mixture.
\n" ); document.write( " \n" ); document.write( "
