Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

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

Answer:
1/21
Step-by-step explanation:
14 = 2/3c ➡ 14×3c=2 ➡ 42c = 2➡ c = 1/21
