Answer:
For every the canoe is rented, the total cost goes up by $12.
Explanation:
To find the proportional relationship, Take two points from the graph, for example (2, 24) and (4, 48), and put them into the slope formula:


Solve:
48 - 24 = 24
4 - 2 = 2
24/2 = 12
The proportional relationship between the hours the canoe is rented and the total cost is $12.
Hope this helps :)
