\n" ); document.write( "Equation:
\n" ); document.write( "tea + tea = tea
\n" ); document.write( "0.50x + 1*6 = 0.80(x+6)
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "50x + 100*6 = 80x + 80*6
\n" ); document.write( "30x = 20*6
\n" ); document.write( "x = 4 oz (amt. of 50% tea to add)
