Final answer:
In the context of the raft rental, the point (0,0) represents the scenario where no hours have been rented, resulting in a total cost of $0.
Step-by-step explanation:
The point (0,0) in this situation represents the starting condition where no time has passed and no money has been spent on white water rafting rentals. It is a common point of reference in mathematics called the origin on a coordinate plane, specifically in the context of linear relationships such as cost functions. If we graph the cost of renting a raft on the y-axis with time on the x-axis, the point (0,0) illustrates that if the raft is not rented for any hours (0 hours), then the total cost would be $0.
