Afruit stand sells 8-ounce containers of blueberries for $4.00. if y represents the cost of x ounces of blueberries, which equation correctly models this proportional relationship?
a. y = 0.2x
b. y = 0.5x
c. y = 2x
d. y = 4x

sine

step-by-step explanation:

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.
