How many liters of an 8% solution of salt should be added to a 24% solution in order to obtain 560 liters of an 16% solution?
\n" ); document.write( ":
\n" ); document.write( "Here's simple method, you don't even need a chart.
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 24% solution required
\n" ); document.write( "The resulting total is to be 560 liters, therefore
\n" ); document.write( "(560-x) = amt of 8% solution
\n" ); document.write( ":
\n" ); document.write( "A simple mixture equation using the decimal equiv of the percent values
\n" ); document.write( ".24x + .08(560-x) = .16(560)
\n" ); document.write( ".24x + 44.8 - .08x = 89.6
\n" ); document.write( ".24x - .08x = 89.6 - 44.8
\n" ); document.write( ".16x = 44.8
\n" ); document.write( "x = 44.8/.16
\n" ); document.write( "x = 280 liters of the 24% solution
\n" ); document.write( "but they want to know the the amt of the 8% solution
\n" ); document.write( "560 - 280 = 280 liters of the 8% solution
\n" ); document.write( "
\n" );
