document.write( "Question 1055108:
\n" ); document.write( "The cooling system of a car has a capacity of 15 liters. If the system is currently filled with a mixture that is 20​% ​antifreeze, how much of this mixture should be drained and replaced with pure antifreeze so that the system is filled with a solution that is 50% ​antifreeze?
\n" ); document.write( "

c for capacity, c=15.
\n" ); document.write( "p for current percent antifreeze in the system, p=20.
\n" ); document.write( "T for the target percent wanted as result in the system, T=50.
\n" ); document.write( "v for volume of current 20% antifreeze to remove and replace with 100% antifreeze to reach T; v is unknown.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How much actual antifreeze in the system now?
\n" ); document.write( "\"c%2A%28p%2F100%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How much actual antifreeze if remove v?
\n" ); document.write( "\"c%28p%2F100%29-%28p%2F100%29v\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How much actual antifreeze when replace with v of 100%?
\n" ); document.write( "\"c%28p%2F100%29-%28p%2F100%29v%2Bv\"\r

\n" ); document.write( "\n" ); document.write( "Total volume of result mixture will be kept the same, c. The target concentration T is wanted.
