Nail polish remover is essentially a mixture of water and a chemical called acetone. How much pure acetone must be combined with a solution that is 19% acetone to make 27 oz of a 37% solution
\n" ); document.write( "======================
\n" ); document.write( "Add A ounces to the 19% solution (S)
\n" ); document.write( "---
\n" ); document.write( "A + S = 27 (total solution)
\n" ); document.write( "100*A + 19*S = 27*37 (total acetone)
\n" ); document.write( "S = 27 - A
\n" ); document.write( "---
\n" ); document.write( "100A + 19(27-A) = 999
\n" ); document.write( "----
\n" ); document.write( "Solve for A
\n" ); document.write( "
\n" );
