The population of Mexico has been increasing at an annual rate of 1.7%. If the population of Mexico was 100,350,000 in the year 2000, predict its population in 2012.

I tried this many times but kept failing at it. Can someone please help me? Thanks

**Henry**, Thursday, March 3, 2011 at 7:54pmPt = Po(1 + rt),

r = 1.7% / 100% = 0.017 = Annual % increase expressed as a decimal.

t = 2012 - 2000 = 12yrs.

rt = 0.017/yr * 12yrs = 0.204.

Pt = 100.35*10^6(1.204),

Pt = 120.8214*10^6 = 120,821,400 = population in 2012.
