If you had to plan on feeding 120 people, two peanut butter sandwiches a week for a year (creamy peanut butter not the crunchy kind, lol). How many large jars of peanut butter would you need to buy? Is this a fun question or what!
1 Large (32 oz) jar of peanut butter. Serving (sandwich) size, 2 tbsp, (32g), Servings per container: 28.
I divided 120 by 28 (the number of people divided by the number of servings in each jar) to get 4.28 ... I rounded it off to 4.3. I doubled checked it by multiplying 28 x 4.3 = 120.4 (which would leave a little blob of peanut butter left over for a snack for the cook, lol).
(28 x 4.3 = 120.4) You would need 4.3 large jars of creamy peanut butter (LOL), to feed 120 people one sandwich. However, if you were going to give them two peanut butter sandwiches a week, then the actual number of peanut butter jars you would need would double to 8.6 large jars of creamy peanut butter. (Is your tongue stuck to the roof of your mouth yet?)
So, now we know to feed 120 people, two peanut butter sandwiches a week, we would need to have 8.6 large jars of creamy peanut butter.
How many jars of peanut butter would you need to feed 120 people, two peanut butter sandwiches for a month? Estimates or guestimates are ok, estimating a month to be around 30 days.
8.6 large jars of peanut butter (two sandwiches for a week) x 4 (average weeks in a month) = 34.4
You would need 34.4 large jars of creamy peanut butter. (LOL), to feed them sandwiches for a month.
How many large jars of creamy peanut butter would you need to feed 120 people, two peanut butter sandwiches a week, for a year? (Guestimates are accepted), LOL.
If it takes 34.4 large jars of creamy peanut butter to feed them for a month, multiply:
34.4 x 12 = 412.8 ... if you rounded it off ... it would be ... 413.
You will need (roughly) 412.8 (413 rounded off) large jars of creamy peanut butter to feed 120 people, two peanut butter sandwiches a week for a year. Guestimates are ok, numbers may differ ... what number did you get?
I can't resist asking another short question: If you had 413 large jars of creamy peanut butter and each jar has 28 servings. How many sandwiches could you make?
413 x 28 = 11,564.
If you wanted to double check your answer, you would:
11,564 divided by 28 = 413 (That's a lot of peanut butter, dude!)
Did everyone get a peanut butter sandwich? LOL
I use to hate questions like this when I was in school because I wasn't sure if the creamy peanut butter weighed more than the crunchy peanut butter and I would get lost in the details of how to construct and answer the question. Adding details like creamy not crunchy and peanut butter sandwiches, complicates a relatively simple math equation. It's a fun question when you think about it. Now, go drink some milk and wash down all that peanut butter in your mouths, lol.
