a chemist has one solution that is 20% saline and a second that is 65% saline. How many gallons of each should be mixed together to get 120 gallons of a solution that is 50% saline.
\n" ); document.write( "=================
\n" ); document.write( "t = 20%
\n" ); document.write( "s = 65%
\n" ); document.write( "---
\n" ); document.write( "t + s = 120 (total solution)
\n" ); document.write( "20t + 65s = 120*50 (total salt)
\n" ); document.write( "---
\n" ); document.write( "Solve for t & s
\n" ); document.write( "
