    Answer:

    Results are below.

    Step-by-step explanation:

    Giving the following information:

    Decrease rate (d)= 7%

    Number of periods (n)= 7 years

    Current population (PV)= 48,000

    First, to calculate the future value, we need to use the following decrease exponential formula:

    FV= PV*[(1+d)^-n]

    After 7 years:

    FV= 48,000*(1.07^-7)

    FV= 29,892
