Jane has 40 liters of 70% acid solution.
\n" ); document.write( " How many liters of water must be added to form a solution that is 40% acid?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of water required to accomplish this
\n" ); document.write( "write an amt of acid equation, remains the same, only the percent changes
\n" ); document.write( ".7(40) = .4(x+40)
\n" ); document.write( "28 = .4x + 16
\n" ); document.write( "28 - 16 = .4x
\n" ); document.write( "12 = .4x
\n" ); document.write( "x = 12/.4
\n" ); document.write( "x = 30 liters of water required
\n" ); document.write( "
\n" );
