In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.
The average American eats an average of 4.2 commercially prepared meals per week. In other words, as a nation, we eat out between four and five times a week, on average.t an average cost of $12.75 per meal, youâd save yourself $8.75 for each of those meals. In other words, the average American would save $36.75 per person per week by moving all of their meals from restaurants to home-prepared meals.
To answer that question we need to know just how much do people spend on food on average on both an average diet and a real food diet. According to the USDA the average family of four is spending somewhere between $544 to $1235 per month for food eaten at home.Thatâs a huge range! They break it down into 4 plans: Thrifty, low-cost, moderate, and liberal.verage Diet Food Budget = $7 a day per person. This USDA plan assumes this family of 4 always eats at home, never at McDonaldâs, Subway, or Applebeeâs. A single meal out can blow the entire days food budget ! Knowing that Americans eat out 5 times a week I consider this a low number.
