Jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. The expression below represents the total number of views that Jackson's video receives n days after he begins tracking the number of views, where b is the rate at which the number of views changes.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
