Solve for r in the formula
\n" ); document.write( "S = L - rL
\n" ); document.write( ":
\n" ); document.write( "Factor out L
\n" ); document.write( "S = L(1 - r)
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by L
\n" ); document.write( "\"S%2FL\" = 1 - r
\n" ); document.write( "Rearrange
\n" ); document.write( "r = 1 - \"S%2FL\"
\n" ); document.write( "
\n" );
