The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.
Hope this helps!
Have a nice day :)

x
= 
-4/100 simplified = -1/25 <em>(because </em><em>4</em><em> goes into </em><em>100</em><em> 25 times)</em>
