Macy wants to change 18 quarts of an 8% solution of ammonia to a 6% solution by adding pure water. How much pure water must she add?
\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "water + water = water
\n" ); document.write( "-----
\n" ); document.write( "0.92*18 + 1*x = 0.94(18+x)
\n" ); document.write( "--------
\n" ); document.write( "92*18 + 100x = 94*18 + 94x
\n" ); document.write( "6x = 2*18
\n" ); document.write( "x = 6 qts (amt. of pure water to add)
