\n" ); document.write( "Here is another non-algebraic method that allows for a non-algebraic solution. It is an especially fast method if you are good with mental arithmetic.

\n" ); document.write( "In the problem, 0% antifreeze is mixed with 60% antifreeze to get a mixture that is 8% antifreeze.

\n" ); document.write( "Observe (perhaps using a number line) that 8% is 2/15 of the way from 0% to 60%.

\n" ); document.write( "That means the 1.6 liters of 60% antifreeze being added is 2/15 of the mixture.

\n" ); document.write( "That means the capacity of the radiator in liters is

\n" ); document.write( "\"%2815%2F2%29%281.6%29=15%280.8%29=12\"
