Posted by Josh on Friday, March 11, 2011 at 12:22am.

I have a maths assignment and i need help with this question my teacher is overseas at the moment and it is due when he gets back

The Population P, of penguins in a certain region of Antarctica can be modeled by the relation P=Po (2) t/90, where t is time, measured in months and Po is the initial number of penguins.

a) if there are 800 penguins in the region today, how many will there be in 2 years?

b) what does the value of 90 represent in this formula?

c) How long will it take before there are 12 800 penguins?
