Rona mixes 2 pounds of meat with some chopped vegetables to make a mixture. She divides the mixture into 4 equal portions. Each portion weighs 3 pounds. Which equation and solution shows the total amount of chopped vegetables she used in the mixture?

Four equal portions weighing 3 pounds each make a total mixture of 4 × 3 = 12 pounds. The mixture contains 2 pounds of meat and v pounds of vegetables, so (2 + v) ÷ 4 = 3, which gives 2 + v = 12 and v = 10. Choice B shows the correct equation and 10 pounds of chopped vegetables.
