A chemist wants to make a 50ml of a 16% acid solution by mixing a 13% acid solution and an 18% acid solution. how many milliliters of each solution should the chemist use.
\n" ); document.write( ".13(50-x)+.18x= 8
\n" ); document.write( "6.5-13x+.18x=8
\n" ); document.write( "6.5+5x=8

\n" ); document.write( "----------------
\n" ); document.write( "Think about what the numbers mean.
\n" ); document.write( "----------------
\n" ); document.write( "t = amount of 13%
\n" ); document.write( "e = amount of 18%
\n" ); document.write( "--------
\n" ); document.write( "t + e = 50 (total solution)
\n" ); document.write( "18e + 13t = 50*16 (total acid)
\n" ); document.write( "---
\n" ); document.write( "Now it's 2 eqns in 2 variables
\n" ); document.write( " \n" ); document.write( "
