You need to use 3 solutions of drug H containing respectively 50%, 20% and 5% to make 600ml of 10% drug H. How much of the 50% will you use
\n" ); document.write( "The right answer 50ml 50% Several teachers already solved this question which is not right.
\n" ); document.write( "I great appreciate Rich for me to solve it again step by step
\n" ); document.write( "This equation is not right
\n" ); document.write( "0.5a + 02%b + 0.05c = 0.1 x 600
\n" ); document.write( "-----------------
\n" ); document.write( "You have 3 variables. You need a statement that relates
\n" ); document.write( "two of those variables.
\n" ); document.write( "You have f + t + v = 600
\n" ); document.write( "You have 0.5f + 0.2t + 0.5f = 0.1*600
\n" ); document.write( "Need one more equation.
\n" ); document.write( "------------------
