To determine which charter company is more cost-effective for a group of 10 customers, we can calculate the total cost for each charter:
Maritime Voyage:
- Boat rental: $250
- Cost per person: $25
- Total cost for 10 customers: \( 250 + (25 \times 10) = 250 + 250 = 500 \)
Catamaran Command:
- Boat rental: $75
- Cost per person: $50
- Total cost for 10 customers: \( 75 + (50 \times 10) = 75 + 500 = 575 \)
Now, we can compare the total costs:
- Maritime Voyage: $500
- Catamaran Command: $575
Since the total cost for Maritime Voyage ($500) is less than the total cost for Catamaran Command ($575), the group should choose Maritime Voyage.
The correct response is: Maritime Voyage; choose this charter for more than 7 customers.
