Since the annual growth is 11% the fox population is (1+0.11) = 1.11 times the value of the previous year.
In 2012 there were 24,100 foxes.
One year later, In 2013 there would be 24,100 * 1.11 foxes.
Two years later, In 2014 there would be 24,100 * 1.11 * 1.11 foxes or 24,100* 1.11^2 foxes.
Seven years later, In 2019, there would be 24,100 * 1.11^7 foxes = 50,035.46 ~ 50,035
