how many quarts of a 15% salt solution must be mixed with 8 quarts of a 25% salt solution to obtain a 17.5% salt solution?
\n" ); document.write( "Let x = amount (quarts) of 15% solution
\n" ); document.write( "then
\n" ); document.write( ".15x + .25(8) = .175(x+8)
\n" ); document.write( ".15x + 2 = .175x+1.4
\n" ); document.write( ".15x + .6 = .175x
\n" ); document.write( ".6 = .025x
\n" ); document.write( "24 quarts = x
\n" ); document.write( "
\n" ); document.write( "
