Final answer:
Option (a) $504 represents the best deal for a four-night reservation as it is the lowest price among the options provided.
Step-by-step explanation:
The student is asking to compare five different final prices to determine which one is the best deal for a four-night reservation. It seems there was some confusion with the provided totals, as they do not directly help to answer the question regarding the final price of the four-night reservation. However, from the options given (a) $504, (b) $512, (c) $555, (d) $580, and (e) $672, the lowest price represents the best deal. In this case, option (a) $504 is the cheapest option and hence represents the best deal for a four-night reservation.
