To determine which charter is cheaper for a group of 10 customers, we need to calculate the total cost for each company.
**For Maritime Voyage:**
- Boat rental: $250
- Cost per person: $25
- Total cost for 10 customers = $250 + (10 * $25)
- Total cost = $250 + $250 = $500
**For Catamaran Command:**
- Boat rental: $75
- Cost per person: $50
- Total cost for 10 customers = $75 + (10 * $50)
- Total cost = $75 + $500 = $575
**Comparison of Total Costs:**
- Maritime Voyage: $500
- Catamaran Command: $575
Since $500 (Maritime Voyage) is less than $575 (Catamaran Command), the group should choose **Maritime Voyage**.
Based on the options provided, the best choice is:
**Maritime Voyage; choose this charter for less than 13 customers.**
