Break Even Point

I am not quite sure is this the right place to post the question here and I sincerly appolgiese if its not.

My question is simple:

There is an offer received by a company from an interested client for use of their facilities for a 3 day event and they are unsure whether this retreat will be money for value.

The info that I have is:

Food for the delegates is expected to cost £70 per delegate over the three day period.
Accommodation will be charged at £120 per delegate for the three day period.

Is “for three day period” and “over three day period” is one and the same and should I consider that 70 and 120 are VC for the whole period/event.

Thank you in advance.
