Old value = $400, new value = $500, percent change = $100 / $400 x 100 = 25% increase. 9) calculate population growth rate and population density. Review sample questions, scoring guidelines, and sample student responses. Explore timing and format for the ap environmental science exam. This commonly shows up on the apes exam. Population density = population divided by area. Web formulas and tables for ap statistics i.
