growth rate= (final-initial)/initial *100
so lets consider this urching
N=Original*2^(t/1.5) in one year
N=Original*2^.666=1.59 original
growth rate=(1.59-1)/1*100= 59 percent per year
1.The estimated doubling time for the black sea urchin population is approximately 1.5 years. What is the annual growth rate of the urchin?
help please?
