How many gallons of a saline solution containing 25% salt must be added to obtain a solution that has 10% salt ? \n" ); document.write( "-------------------------------------- \n" ); document.write( "Equation: \n" ); document.write( "salt + salt = salt \n" ); document.write( "0*100 + 0.25x = 0.10(x+100) \n" ); document.write( "Multiply thru by 100 and solve for \"x\" \n" ); document.write( "0 + 25x = 10x + 1000 \n" ); document.write( "15x = 1000 \n" ); document.write( "x = 66 2/3 gallons of 25% saline solution must be add \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
