Answer: There would be 2240 Foxes after 39 years
Step-by-step explanation:
The population of 35 foxes in a wildlife preserve quadruples in size every 13 years. The population growth is modelled by the function,
y = 35 * 4^x
Where
x represents the number of 13-year periods.
In a period of 39 years, the number of of 13-year periods is
39/13 = 3
Since the are three 13-year periods, substituting x = 3 into the function, it becomes
y = 35 * 4^3
y = 35 × 64
y = 2240
