I would not look at the nbr of servings but @ the calories they provide. 1 per person is probably recommended.

I've recently been using this stuff that I found at a home show here in Nashville -- I just buy in bulk and then just repackage for whatever my needs are -- long trip, short trip, trailmixes, etc. They also have some MRE's and basic survival gear. I haven't price compared on the gear, but it's not really anything that I need.
