**Reiny**, Friday, July 29, 2011 at 11:34amlet N = 15 e^(kt), where N is in million, t is in years since 1991 and k is a constant

when t = 10 , N = 16

16 = 15e^(10k)

1.0666667 = e^(10k)

ln 1.0666667 = 10k

k = .006456852

then when t = 14

N = 15e^(14(.00645852)) = 16.418

So to the nearest million it would still be 16 million
