    We are given with the initial population and is asked for the final population after n years. in this case, we use the formula P (n) = Po * (1 + r) ^n where r is the rate of growth. 1) P (n) = Po * (1 + r) ^n P (n) = 8600 * (1 + 0.03) ^3 P (n) = 9397 people

    2) P (n) = Po * (1 + r) ^n P (n) = 1500 * (1 + 0.02) ^4 P (n) = 1624 deers
