7%

Step-by-step explanation:

if you divide the difference between the two numbers it will give you a decimal you need to convert that decimal into a percent which is 7%

mark me brainlest

because they could drop even lower..

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.
