seller has 80kgs of peanuts worth $1.50/kg and 50 kg of cashews worth $4.50/kg.
\n" ); document.write( " he wants to make a 100 kgs mixture to sell at $2.61/kg .
\n" ); document.write( " find the number of kgs of cashews and peanuts sold.
\n" ); document.write( ":
\n" ); document.write( "let x = amt of $4.50 cashews
\n" ); document.write( "total mixture is 100 kg, therefore:
\n" ); document.write( "(100-x) = no. of $1.50 peanuts
\n" ); document.write( ":
\n" ); document.write( "4.5x + 1.5(100-x) = 2.61(100)
\n" ); document.write( "4.5x + 150 - 1.5x = 261
\n" ); document.write( "4.5x - 1.5x = 261 - 150
\n" ); document.write( "3x = 111
\n" ); document.write( "x = 111/3
\n" ); document.write( "x = 37 kg of cashews
\n" ); document.write( "then
\n" ); document.write( "100 - 37 = 63 kg of peanuts
\n" ); document.write( ":
\n" ); document.write( " how many cashews are left over at the end?
\n" ); document.write( "50 - 37 = 13 kg left over \n" ); document.write( "
\n" );
