Final answer:
Cruise deposits vary by line and itinerary; without specific cruise line data, we can't determine the deposit for a 6-day cruise. The provided info on bills for a 7-day cruise can estimate spending but doesn't indicate deposits.
Step-by-step explanation:
The question seems to be asking about the onboard bills rather than a deposit amount. Nevertheless, cruise deposits vary significantly by cruise line, itinerary, and length of the cruise. Information provided about the cruise bills from Los Angeles to the Mexican Riviera indicates that 60 single travelers and 70 couples (which would account for 140 individuals if each couple consists of two people) were surveyed, but does not directly give us a deposit amount.
To determine the deposit required per person for a 6-day cruise, one would typically need to check with the specific cruise line for their deposit requirements, as this can range from a small percentage of the total fare to a fixed amount per person, depending on the cruise line's policies. The summary of the bills for the group can help estimate total onboard spending but isn't directly related to the deposit amount, since the full bill is settled at the end of the cruise. For exact deposit details, it's necessary to contact the cruise line or review the terms at the time of booking.
