Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by 
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is 
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is 
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is 
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is
