  1. 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
