how many 20% acid solution should be mixed with 6 oz of 30% acid solution to produce a mixture that is 28% acid?
\n" ); document.write( "------
\n" ); document.write( "Sketch 3 jugs
\n" ); document.write( "Start jug has x oz of 20% solution
\n" ); document.write( "Second jug as 6 oz of 30% solution
\n" ); document.write( "Result jug has (x+6)oz of 28% solution
\n" ); document.write( "-------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "0.20x + 0.30*6 = 0.28(x+6)
\n" ); document.write( "--------
\n" ); document.write( "20x + 30*6 = 28x + 28*6
\n" ); document.write( "----
\n" ); document.write( "8x = 2*6
\n" ); document.write( "x = 12/8 = 3/2 oz (amt. of 20% to add)
\n" ); document.write( "-------------------
