We write this inverse relationship as
\n" ); document.write( "y = k/x
\n" ); document.write( "or in this case
\n" ); document.write( "n = k/p
\n" ); document.write( "now plug in to find k
\n" ); document.write( "70 = k/1.50
\n" ); document.write( "k = 105
\n" ); document.write( "now rewrite it using the found k
\n" ); document.write( "n = 105/p
\n" ); document.write( "and plug in the new data to find n
\n" ); document.write( "n = 105/1.25
\n" ); document.write( "n = 84 \n" ); document.write( "

\n" );
