Suppose that the water in a swimming pool initially has a chlorine content of 4 parts per million, and 15 percent of the chlorine dissipates each day. If no additional chlorine is
added, write the explicit formula for a sequence that gives the chlorine concentration at
the beginning of each day.
an = 0.15(4)n-1
an= 0.85(4)n-1
an= 4(0.85)n-1
an = 4(0.15)n-1

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.

hope this .
