**Reiny**, Monday, November 1, 2010 at 6:21pmI will assume that t is the time in years since 2004

P(t) = 166 e^(.015t)

a)

so for 2016 , t = 12

P(12) = 166 e^(12(.015)) = 166 e^.18 = 198.7 thousand or 199 thousand

b) 258 = 166 e^.015t

1.55422 = e^.015t

.015t = ln 1.55422

t = ln1.55422/.015 = 29.4 years since 2004

or in the year 2033
