Answer:
15 students per month
Step-by-step explanation:
The rate of change is calculated as
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
f(b) = 95 ← number of students in October
f(a) = 65 ← number of students in August
b - a = 2 ← difference in months
Thus
rate of change = [tex]\frac{95-65}{2}[/tex] = [tex]\frac{30}{2}[/tex] = 15
The rate of change is the ratio between the change in the y and x coordinates. The students ranged from 65 to 95 in two months, so the rate is
[tex]\dfrac{95-65}{2}=\dfrac{30}{2}=15[/tex]
