To determine which charter is more cost-effective for a group of 10 customers, we can calculate the total cost for each charter company.
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:
\( 75 + (50 \times 10) = 75 + 500 = 575 \)
Comparing the total costs:
- Maritime Voyage: $500
- Catamaran Command: $575
Since $500 (Maritime Voyage) is less than $575 (Catamaran Command), the group should choose Maritime Voyage.
In conclusion, the correct response is Maritime Voyage; choose this charter for less than 13 customers.
