There are 400 liters of a 16% solution in container A. There is a pure solution (100%) in container B. If the goal is to make a 20% solution, how many liters of the pure solution from container B must be added to container A
\n" ); document.write( "--------------
\n" ); document.write( "16*400 + 100*B = 20*(400+B)
\n" ); document.write( "Solve for B\r
