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 .
Answer:
160 off 20p coins
Step-by-step explanation:
- 1 p, 20 p, 5 p coins
