There are 17 members in the scout troop. All of the members went on a trip to a state park. There were also 4 adults on the trip. What was the total cost, c, if the admission for each person was $3?
I think the answer is probably either A. because when I was doing and checking my work I added all the people together and times it by 3 and it turns out to be 63. Hope I'm right.
