Answer:

y=25,700(0.85)^{x}

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

y=a(b)^{x}

where

y ----> represent the pool’s loss of water

x ----> the number of days

a is the initial value

a=25,700 gal

b ----> is the base

r=15%=15/100=0.15

b=(1-r)=1-0.15=0.85

The function is equal to

y=25,700(0.85)^{x}
