In fishery science, a cohort is the collection of fish that results from one annual reproduction. it is
usually assumed that the number of fish n( t ) still alive after t years is given by an exponential function. for pacific halibut, n( t ) = n0e ^-0.2t , where n o is the initial size of the cohort.
approximate the percentage of the original number still alive after 7 years. round to one decimal place, if necessary.
