This is what I would do:
60x120 divided by 30 which gets you 240 seals. (Using the formula)
Now this is only 89% of 2008's total population. So then 240 divided by 89 (which gives 1%), then times by 100 to give you the desired amount which is 269.66..., rounding up to give 270 seals
good question, I think they might give it to you considering you knew how to do the steps and showed working out, but put in the wrong numbers.i wrote the capture/recapture formula correctly, but in the midst, i experienced a coughing attack and suddenly substituted in the wrong numbers. do you think ill get marks for a follow through error?
