6) Using your equation, predicted population of the students in 2011.

Answer 1

well, the assumption is that the population is growing on a steady 83 students per year, so we're in 2005 and there are 1118 students, how many were there 5 years earlier? namely in 2000, well, is just 1118 - 83 - 83 - 83 - 83 - 83 = 703.

hmmm what's the equation? well Check the picture below.
