QuestionEntertainment A group of 3 friends is planning a fun day trip. To raft down a river costs $\$ 6$ per person plus $\$ 20$ for transportation of the raft. An amusement park costs $\$ 11$ per person. A hot air balloon ride costs $\$ 30$ per person, but they have a $\$ 50$ group discount coupon. \begin{tabular}{|lr|} \hline Activity & \multicolumn{1}{c|}{ Cost (\) } \\ \hline Raft trip & 6 n+20=38 \\ Amusement Park & 11 \mathrm{n}=38 \\ Balloon Ride & 30 n-50=38$ \\ \hline \end{tabular}
The table shows equations for the total cost of each activity for $n$ people. Which activity should they choose if they want to spend exactly $\$ 38$ ?
The $\square$ would cost exactly $\$ 38$. amusement park balloon ride raft trip
