The hidden question in this scenario is "How many people went on the trip?"
To solve for the total cost \( c \):
-
Count the total number of participants:
- Number of scout members: 17
- Number of adults: 4
Total participants = 17 (members) + 4 (adults) = 21 people
-
Calculate the total cost:
- Admission cost per person = $3
- Total cost \( c = 21 \text{ people} \times 3 \text{ dollars/person} = 63 \text{ dollars} \)
Therefore, the solution is: How many people went on the trip? c = $63
