This depends on densities and how the percent is intended. ASSUMING you are dealing with %v/v, set the equation as this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x = VOLUME of the 25% solution to add.
\n" ); document.write( "\"highlight_green%2825x%2F%28x%2B1%29=2.8%29\".
\n" ); document.write( "Solve for x. The result for x is VOLUME as GALLONS.
\n" ); document.write( "
\n" );
