    Answer: the population be after 10 years is 289145

    Step-by-step explanation:

    The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

    y = b (1 + r) ^t

    Where

    y represents the population after t years.

    t represents the number of years.

    b represents the initial population.

    r represents rate of growth.

    From the information given,

    b = 210000

    r = 3.25% = 3.25/100 = 0.0325

    t = 10 years

    Therefore,

    y = 210000 (1 + 0.0325) ^10

    y = 210000 (1.0325) ^10

    y = 289145
