## nuccioreggie one year ago A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

the unit price is given by the subsequent ratio: 3/4 =...?

4. Michele_Laino

part B: 6 is the price for 8 pounds of potatoes

5. nuccioreggie

Ok but @Michele_Laino. It say i have to show my work and the proportion i used to determine the price

7. Michele_Laino

part A. I call with p the price of 1 pound of potatoes, so I can write this proportion: $\Large 3:4 = p:1$

8. nuccioreggie

Im talking about in words @Michele_Laino

@Michele_Laino

10. Michele_Laino

here is my answer: "three over four is equals to p over one"

O ok and what is B @Michele_Laino

13. nuccioreggie

???

14. Michele_Laino

Part B: "6 is the price of 8 pounds of potatoes"

15. nuccioreggie

How did we get that / know that

16. nuccioreggie

@Michele_Laino. In part A how did you come up with that answer

17. Michele_Laino

since if 4 pounds cost \$3 than 1 pound costs p, namely those ratios 4/3 and 1/p have to be equal each other: $\frac{4}{3} = \frac{1}{p}$

18. Michele_Laino

or, taking the inverse of those ratios, we can write: $\frac{3}{4} = \frac{p}{1}$

Ok thank you i have 3 more ok
