2. the amount paid for different weights of oranges at a farmer’s market are shown below. oranges (lb) price ($) 2 3.00 3 4.50 5 7.50 ? 12.00 (a) is the relationship between the price and the weight of the oranges proportional? use the first three rows of data to answer this question. show your work and explain. (b) how many pounds of oranges cost $12? show your work.

To know if there is a relation between the price and weights of oranges. we must calculate the unit price for each given set of data.for the first data 2 lb, $ 3so the unit price is $3 / 2 lb = $ 1.5 / lb
for the second data 3 lb, $ 4.50the unit price = $ 4.50 / 3 lb = $ 1.5 / lb
third data, 5 lb , $7.50the unit price = $ 7.50 / 5 lb = $ 1.5 / lb. so they have a linear relationship.
lb oranges = $ 12 ( 1 lb / $ 1.50) = 8 lb of oranges cost $ 12
