Answer 1

Answer:

70 students were the average population for each year.

Step-by-step explanation:

Five years ago the population at liberty middle school = 1600 students

Now population is = 1250 students

$\text { Using the expression }=\frac{(n-p)}{5}$

Where n = represent now year's population  

p = represents the previous year population

n = 1250 students

p = 1600 students

$\text { According to the given expression }=\frac{(1250-1600)}{5}$

$=\frac{-350}{5}$

= -70

Therefore, the average change in population each year is 70 students.
