how many pounds of coffee worth $8.00 should be added to 10 pounds of coffee worth $5.00 a pound to get a mixture worth $6.00 a pound\r
\n" ); document.write( "\n" ); document.write( "Let x be the amount of $8.00 coffee. Then when we are finished the total amount of $6.00 coffee we will have is 10 + x.\r
\n" ); document.write( "\n" ); document.write( "So:\r
\n" ); document.write( "\n" ); document.write( "10*5.00 + x*8.00 = (10+x)*6.00
\n" ); document.write( "50 + 8x = 60 + 6x
\n" ); document.write( "2x = 10
\n" ); document.write( "x = 5
\n" ); document.write( "
