Question

 (FULL QUESTION BELOW)

A coffee shop uses 873 coffee cups every 7 days. Which is a reasonable estimate for the number of cups the coffee shop uses in 4 weeks?

Answer 1

What does it mean to USE 873 coffee cups every 7 days? Are these disposable (one-time use) cups?  If so, then you're talking about 4 weeks, so multiply 873 by 4 or if estimation is desired, multiply 900 by 4 to get an estimate of 3600.

 

If the cups are not disposable, then presumably the same 873 cups get used during 4 weeks assuming no breakage or theft).
