From this sentence, we can create a direct variation formula:
\n" ); document.write( "The volume, V, of a tank varies directly with its height, h
\n" ); document.write( " $\"V+=+kh\"$
\n" ); document.write( "step 1 - put in the numbers you are given to find k. the numbers were
\n" ); document.write( "h = 12, V = 300. SO, we get
\n" ); document.write( " $\"300+=+k%2A12\"$
\n" ); document.write( "solving for k, we get
\n" ); document.write( "K = 75.
\n" ); document.write( "step 2 - rewrite the equation with your new k value as
\n" ); document.write( " $\"V+=+75h\"$
\n" ); document.write( "we are done. \n" ); document.write( "

\n" );
