Answer:
42 animals
Step-by-step explanation:
The formula for Exponential decay is given as
y = a (1 - r)^t
Where
y = Population after time t
a = Initial population or size = 60 animals
r = rate of decay = 3.5 % per year = 0.035
t = Time = 10 years
Hence,
y = 60 × (1 - 0.035)¹⁰
y = 60 × 0.7002822742
y = 42.016936449 animals
Approximately = 42 animals
Therefore, the population of that species be after 10 years is 42 animals
