A boat can carry 582 passengers to the base of a waterfall. A total of 13,105 people ride the boat today. All the rides are full except for the first ride. How many rides are given?

582 passengers on the boat
Let r be the number of rides

So we want to find r when:
582r = 13105

To solve for r, we type this equation into our math engine and we get:
r = 22.517

If we round this down, setting 0.517 rides as the first ride, we get:
r = 22
