I understand A and B but I do not understand what they are asking for C. I have no idea what the answer is, please help! Thanks

Mike sells grapes at a farmers market. Each pound of grapes sells for the same amount. The table below shows the total prices for different numbers of pounds of grapes sold.

Grapes
Number of Pounds Sold Total Price ($)
2 $4.50
4 $9.00
10 $22.50


A. Write an equation that describes the relationship between the number of pounds of grapes sold(x) and the total price (y), in dollars.

Mike also sells red peppers at the farmers market. The equation below can be used to find the total price (p) in dollars of r pounds of red peppers.

p = 1.80r

B. What is the total price, in dollars, of 17 pounds of red peppers? Explain what the 1.80 represents in the context of the situation.

The farmer decides to increase the price per pound of the grapes. A graph is created to represent both the original equation from Part A and a new equation based on the increased price per pound of the grapes.

C. Thinking about what this graph would look like, explain why the graphs representing the equations will share one point even though the prices per pound are different.
