population calculation biology homework?

1. population density=500/KM^2 total area=5km^2

mortality( death rate) = 600/yr

natality( birth rate)= 800/yr

emigration= 250/yr

immigration= 50/yr

what is the population /km^2 after 2 years

to be honest I have no idea how to do this problem and if someone could please help me I would greatly appreciate it and please show the steps too so i know how to do it in the future once again thanks for everything you guys....=)

    Population = population density * area

    Initial population = 500/km^2 * 5km^3 = 2500 people

    Change in population = natality + immigration - mortality - emigration Change in population = 800/year + 50/year - 600/year - 250/year

    Change in population = 0/year

    Total change = 0/year*2 years = 0

    Final population = initial population + total change

    Final population = 2500 + 0

    Final population density = final population / total area

    Final population density = 2500/5km^2 = 500people/km^2
