Suppose the cost of 10 pounds of grapes at stall a is $15. would the relationship will be proportional? explain

The relationship is proportional.

Step-by-step explanation:

The cost of 10 pounds of grapes at stall A is $15.

So, the price rate of grapes is dollars per pound.

So, the relation between the weight (w, in pounds) and the price of grapes (c, in dollars) are related as  

c = 1.5w ......... (1)

So, from the above equation, we can say that the relationship is proportional. (Answer)
