    Growth of Population

    The growth in the population of a certain rodent at a dump site fits the exponential funciton A(t) = 336e^0.031t, where t is the number of years since 1963. Estimate the population in the year 2000.

    CHOICES:

    a. 529
    b. 1058
    c. 1091
    d. 347



    MY WORK:

    2000 - 1963 = 37

    So, let t = 37

    A(37) = 336e^0.031(37)
    A(37) = 336e^(1.147)
    A(37) = 336^(3.148732529)
    A(37) = 90775515.48

    My answer is different from the choices given.
    What did I do wrong?

    A(37)=336{\color{blue}\times}3.148732529
