summed up to quite a lot of money

One of my students wrote:

I did not perceive them as hospitable as described. Most of the people were polite, but they usually expected tips, which summed up to quite a lot of money during the stay.

Is it possible to say to sum up to in that context? If it is not, how would you express the student's idea? Could added up to be used?

    I woudl prefer added up there, yes. That is a very idiomatic expression. The student's offer is close, but not how we use summmed up.

    "To sum up" is usually used in the context of words rather than numbers, when someone sums up a discussion, for example by "summarising" the key points.
