A population exhibits a finite rate of increase of 1.91. After 10 generations, the population size is 146000 individuals. What was the initial population size? Assume the population grows exponentially. The formula is Nt = N0 ertd , Solve for N0. I\'m having issues with this problem. I just dont think I\'m using the formula correctly. Solution Nt = N0 ert Nt = 146000 r=1.91 t= 10 146000= N0 e0.0191(10) 146000 = N0 (1.21) N0 =120661.
