To conduct a new experiment, a scientist needs a 23% salt water solution. How much of a 10.5% solution must be mixed with 25 pints of a 39% solution to get the proper solution?
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "0.105x + 0.39*25 = 0.23(x+25)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 1000.
\n" ); document.write( "105x + 390*25 = 230x + 230*25
\n" ); document.write( "--------------------------
\n" ); document.write( "125x = 160*25
\n" ); document.write( "----
\n" ); document.write( "x = 32 pints (amt. of 10.5% solution needed for the mixture)
\n" ); document.write( "=====================
