Every few years, Edgar's entire family gets together for a family reunion. This year, Edgar's parents are hosting, and they have to cook a lot of food to feed the crowd. Edgar has volunteered to do the most tedious job: shelling peas. There is a proportional relationship between the amount of time (in minutes) Edgar spends shelling peas, x, and the weight (in pounds) of the peas he has shelled, y.
The equation that models this relationship is y=0.5x.
How many pounds of peas does Edgar shell in 16 minutes? Write your answer as a whole number or decimal.
