Match the real-world problem to its constant of proportionality.
$4.16 for 4 pounds of bananas
$16.48 for 8 pounds of potatoes
$18.36 for 2 pizzas
2 cups of flour to make 36 cookies

9.18,1.04,18,2.06

Real word problem ⇒ constant of proportionality

$4.16 for 4 pounds of bananas ⇒ 1.04

$16.48 for 8 pounds of potatoes  ⇒ 2.06

$18.36 for 2 pizzas  ⇒ 9.18

2 cups of flour to make 36 cookies ⇒ 18

Solution:

A proportional relationship is one in which two quantities vary directly with each other.

We say the variable y varies directly as x,

if for x ∝ y

then,  x = y k

Where "k" is called constant of proportionality

$4.16 for 4 pounds of bananas

x = 4.16 and y = 4

Thus constant of proportionality is 1.04

$16.48 for 8 pounds of potatoes

x = 16.48 and y = 8

Thus constant of proportionality is 2.06

$18.36 for 2 pizzas

x = 18.36 and y = 2

Thus constant of proportionality is 9.18

2 cups of flour to make 36 cookies

x = 36 and y = 2

Thus constant of proportionality is 18

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
