The drag force (D) of an object falling through air varies directly as the square of its velocity (v). What is the correct expression to model this relationship?

D = kv^2, where k is a non-zero constant

Step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
