Solve the system of equations using substitution. 2x + 8y = 24
-2x + y = 12
A (-7,-4)
B (-4,4)
(-4,-7)
(-7,4)

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.
