Can you calculate how many tennis balls are used during the course of Wimbledon

None - they're all brand new.

Yes

54,250, according to the Wimbledon website

Number is irrelevant here. Brand is the important and how they have been successful to get their balls to there!

Ok, so, this is coming from a senior (read older) person who has had quite a lot of experience with this kind of stuff. The question is designed not so that you provide a quant kind of answer. It’s designed so that you formulate what kinds of questions to ask. Like: “who is asking this question?”, “what is the aim and focus of the question(to reduce ball consumption? To get a new client to supply balls?)? Who do I speak to to find out how many balls were consumed over a period of time? Is consumption rising/falling/stable? Is the quality of balls an issue? Is this just a simple maths equation or are you asking me to dig deeper. If you just answered with a flat guesstimated number above, what model were you basing this on and where could there be a margin for error?
