how many liters of a 90% acid solution must be mixed with a 15% acid solution to get 600 liters of a 80% solution?
\n" ); document.write( "=======================
\n" ); document.write( "n = liters of 90%
\n" ); document.write( "f = liters of 15%
\n" ); document.write( "----
\n" ); document.write( "n + f = 600 ---------- total solution
\n" ); document.write( "90n + 15f = 600*80---- total acid
\n" ); document.write( "---
