Using algebra tiles, the area model below models the
multiplication of two binomials.

Just add the given values in the algebra tiles :

if i put something wrong your not gonna like it so rather not say nothing.

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.
