If $\"T\"$ varies directly with $\"S\"$ , we know that $\"T=kS\"$ for some constant $\"k\"$ . We know that if $\"S=9\"$ , then $\"T=36\"$ . We can plug this into the equation to get $\"36=k%2A9\"$ . Solving for $\"k\"$ , we get $\"k=4\"$ . Therefore, $\"T\"$ and $\"S\"$ are related by the equation $\"T=4S\"$ . Finally, we can plug in $\"S=2\"$ to get $\"T=4%2A2=highlight%288%29\"$ . \n" ); document.write( "
