\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "value + value = value
\n" ); document.write( "60x + 90*50 = 80(x+50)
\n" ); document.write( "60x 4500 = 80x + 4000
\n" ); document.write( "-20x = -500
\n" ); document.write( "x = 25 lbs (amt. of $60 coffee needed)
