differential equations help?from sample sac

[geeza23]

i got like a sample sac and its basically this
the population of like certain species of animals can be modeled after dW/dt=(m-n)W where W is the population of the animal after t time
and for part i m=0.10 and n=0.06 and find out the population after 10 and 100 years and then ii use eulers rule to find out the population after 10 years and then compare the results between i and ii

part b is 0.08 < or equal to m < or equal to 0.12
            0.06 < or equal to n < or equal to 0.09
find an expression for the number of animals using like reasonable values of m and n
then find at when i)will they all die out
                        ii)grow with no limit


can anyone help me out?

not sure what the question is asking...
-with euler's rule: usually a step size is included with initial conditions
-also when constructing a differential equation usually part of the question says "initially there were ___ animals" so that you can find the constant after you integrate it.

So far i end up with

W = e^((1/25)(t-c)) by flipping dW/dt and then integrating and rearranging it.
need more information to find c.
