Answer 1

$k =1.89$ 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:

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  :

$y = (k)x$ , where k is constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

⇒ $y = (k)x$

⇒ $3.78 = (k)2$

⇒ $\frac{3.78}{2} = \frac{(k)2}{2}$

⇒ $\frac{3.78}{2} =k$

⇒ $k =1.89$

Therefore, $k =1.89$ is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .
