Certainly the law of large numbers has application here because of the term average. It would seem one would have to know how many people actually go out to eat on a consistent basis and how many meals they purchase in a given period. some go out 5 days a week and some eat out only 5 times a year.You can't combine these stats and come up with an average. Either way eating out can be expensive and the question of eating healthy also comes into play.
