The discriminant is

A. aX2 + bX + c
B. b - 4ac
C. b2 - 4ac
D. b2 + 4ac

B) b²-4ac

Step-by-step explanation:

The answer is B because that is the discriminant in the quadratic formula.

(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).
