Guest: what is the average unit of sale. serves 2100 in meals to 115 customers
Hi Guest,
I think that you are being asked what is the average number of meals per cusomers.
-----------------------------------------------------------
I just want to talk about non-related things first.
now three people get these marks in a test 4, 7, and 2
Then the average mark is the total of all the marks divided by how many marks there were. That is (4+7+2)/3
------------------------------------------------------------
Now in your question you have already got the total number of meals, that was already added for you.
And you have got the number of customers.
So can you work out the average number of meals per cusomer by yourself now?
