Exponential change can be modeled by: N = N(0) x λⁿ; where λ is the rate of change. It is greater than 1 when there is growth and less than 1 when there is decay. n is the number of time periods passed. λ is 1 + 0.083 = 1.083 N(0) is the initial value of 750 n is 2050 - 2005 = 45 years N = 750 x (1.083)⁴⁵ = 27,000 fish
