is the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
<u>Step-by-step explanation:</u>
Here we have , The cost of 2 pounds of potatoes is $3.78. We need to find the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x . Let's find out:
Cost is y & number of pounds of potatoes is x :
, where k is constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
⇒
⇒ 
⇒ 
⇒ 
⇒
Therefore, is the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .

Step-by-step explanation:
Answer:
E = 8
Step-by-step explanation:
y - x = 4
y - (3y) = 4
y - 3y = 4
2y = 4
y = 4/2
y = 2
x = 3y
x = 3×2
x = 6
x + y = 2+6
x+y = 8
