Let x=amount selling for $3 per lb \n" ); document.write( "Then 80-x=amount selling for $4 per lb\r \n" ); document.write( "\n" ); document.write( "Now we know that the total amount of dollars generated by selling the candy separately would have to equal the total amount of dollars generated by selling the 80 lb mixture. Therefore, our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "$3x+(80-x)($4)=(80)($3.60) simplifying, we get: \n" ); document.write( "3x+320-4x=288 \n" ); document.write( "-x=-32 or \n" ); document.write( "x=32 lb of $3 candy \n" ); document.write( "80-x=80-32=48 lb of $4 candy\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps -----ptaylor\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
