Answer:
6.12
1.39
4.12
12
Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by [tex]k = \frac{y}{x}[/tex]
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is [tex]\frac{18.36}{3} = 6.12[/tex]
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is [tex]\frac{4.17}{3} = 1.39[/tex]
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is [tex]\frac{16.48}{4} = 4.12[/tex]
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is [tex]\frac{24}{2} = 12[/tex] (Answer)
