A merchant wants to mix peanuts worth $3 per pound with jelly beans worth $1.50 per pound to make 40 pounds of a mixture worth $2.10 per pound. How many pounds of each should he use?
\n" ); document.write( "***
\n" ); document.write( "let x=lbs of peanuts to mix.
\n" ); document.write( "let y=lbs of jelly beans to mix
\n" ); document.write( "x+y=40
\n" ); document.write( "y=(40-x)
\n" ); document.write( "..
\n" ); document.write( "3x+1.50y=40*2.10
\n" ); document.write( "3x+1.5(40-x)=40*2.1
\n" ); document.write( "3x+60-1.5x=84
\n" ); document.write( "1.5x=24
\n" ); document.write( "x=16
\n" ); document.write( "y=40-x=24
\n" ); document.write( "lbs of peanuts to mix =16
\n" ); document.write( "lbs of jelly beans to mix=24
\n" ); document.write( "
\n" );
