Answer 1

Answer:

Rate of change is increase of 51 followers per year.

Step-by-step explanation:

Given:

Number of followers in 2012 = 74

Number of followers in 2015 = 227

Therefore, increase in followers = 227 - 74 = 153

Duration for the change = 2015 - 2012 = 3 years

Rate of change of followers is given as:

$\textrm{Rate of change}=\frac{Increase}{Duration}=\frac{153}{3}=51$

Therefore, rate of change is increase of 51 followers per year.
