Anwser the following

7.99

Step-by-step explanation:

if x = 1.7

x² = 2.89

3x = 3 times x = 5.1

2.89 + 5.1 = 7.99

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
