step-by-step explanation:
y=mx+b
constant of proportionality = 3 and the equation is c = 3p.
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.
