It is 32.8 I just did %in my class today
        
             
        
        
        
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
 
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0  would just be equal to 1. Therefore
the original population is 
16,800. 
 
Answer: B. 16,800

There are the same signs so you'd just add them together and use whatever sign they are..
