11. The GSS Graduating Class wants to have an “end of the school year celebration.” They must decide between Wild
Water Works or Canada’s Wonderland. The cost of each trip is described below:
Wild Water Works: $200 to rent a bus, and $15 per student for admission to the park
Canada’s Wonderland: $800 to rent a bus, and $12 per student for admission to the park.
Let “n” stand for the number of students who go on the trip.
Let “C” stand for the TOTAL cost of the trip.
