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
