Answer: After 30 years there will be 540
Step-by-step explanation:
The function that models the the population growth of the foxes in the wildlife reserve is expressed as
y = 60 times 3^x,
Where
x represents the number of 15-year periods.
The initial number of foxes in the wildlife is 60
Since the population the foxes in the wildlife preserve triples in size every 15 years, in 30 years,
x = 30/15 = 2
Therefore,
y = 60 × 3²
y = 540 foxes
