How many liters of water should be evaporated from 60 liters of a 28% salt solution so that the remaining solution contains 32% salt?
\n" ); document.write( "---------
\n" ); document.write( "Equation:
\n" ); document.write( "water - water = water
\n" ); document.write( "0.72*60 - x = 0.68(60-x)
\n" ); document.write( "-------------------------------
\n" ); document.write( "72*60 - 100x = 68*60 - 68x
\n" ); document.write( "------
\n" ); document.write( "-32x = -4*60
\n" ); document.write( "-----
\n" ); document.write( "x = (1/8)60
\n" ); document.write( "x = 7.5 liters (amt of water to evaporate)
\n" ); document.write( "-----------
