Question

A demographer develops a model for the population, P, of a small town n years from today such that p(n)=-0.15n^5+3n^4+5560

a)When will the population of the town be between 10242 and 25325?

How would I go about doing this question? I understand inequalities but I don't see what the inequality would be here. I just need to know what I need to write after the equation (eg. >= or <)

You need to make 'double' inequality or the system of inequalities, have you ever heard of them?

Not really, been doing these in my textbook and all of them including the examples given are just single inequalities. Could you explain how I would proceed with this question with double inequalities?
