It starts off with a pop. of 177,000 and multiplies by 1 for itself and .013 for the 1.3%. It is at a power of t because the percent of change will increase value the more years the population grows.
1.013 x 1.013 = 2 years and 1.013 x 1.013 x 1.013 = 3 years and so on.
you have to calculate the SID number and then take it upon yourself and divided X it's actual number and then there's a chance and the answer would be c.72
