That is what I would do.
A biologist introduces 200 ladybugs into a crop field. The populationP of the ladybugs is approximated by the model:
Where t is the time in days. Find the time required for the population to increase to at least 2000 ladybugs.
Ok so for this one do you make P=2000 and solve it for t, is it that simple or am i missing something?
