You can put this solution on YOUR website!
(percent mixture wanted) = (amount of pure drug)/(mixture)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Amount of just the drug is \"0.16%2Ax%2B0.28%2Ay\"
\n" ); document.write( "Amount of mixture obviously was given, 15 ml.
\n" ); document.write( "This uses x for amount of the 16 drug and y for the amount of the 28% drug.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The FRACTION of the mixture as drug we want is 0.24, which means same as 24%.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Put everything in place:
\n" ); document.write( "\"%280.16x%2B0.28y%29%2F15=0.24\" AND \"x%2By=15\"
\n" ); document.write( "Solving this system should not be any trouble.\r
\n" ); document.write( "\n" ); document.write( "
