The things that Sarah needs to know include the size of the pizza as well as the crowd capacity and how many slices come with each pizza. In this case, we can say that she would need at least 2 boxes of pizza for all the people in the gathering to have at least one slice or 4 to 5 boxes from them to have at least 2 slices each.

Hope This Is Right
Cellular respiration occurs in the mitochondria, the double membrane organelle. It occurs when the cells need energy, storage molecules like glycogen are rapidly broken down from being a polysaccharide to its monomer units which undergo reactions once transported to the cells requiring energy and broken down to release its energy.
Yes, there is a situation where living cells are not respiring. For example in the microbial cell that lives in anaerobic environments in specific environments will use fermentation instead of respiration to produce ATP. The example of this is the yeast cells in beer mash.
