Step-by-step explanation:

Hope that helps :)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

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.
