The caribou population of an area has been growing at an annual rate of 2% ,
A) If there are 850 initially, how long before there is a 1000?

B)How long for it to double?

x
1000=850(1.02)

  • Math -

    P = Po(1+r)^t = 1000.
    850(1.02)^t = 1000
    (1.02)^t = 1000/850 = 1.17647
    Take Log of both sides:
    t*Log 1.02 = Log 1.17647
    0.0086t = 0.07058
    t = 8.2 Years
