If this is the only criteria that your page is failing on, i wouldn't worry about it too much.
If you think having 48 occurences of your keyword is beneficial to the user of the site i would leave it as is.
edit: From your info above it would suggest that you have 39 occurences in the body of your text. This does actually sound a little bit over the top. If you're able to get this down to around 6 i think your customers would find you content more useful.
