conversations.value: Can you explain how to solve this math problem: Jo has been making face masks. She can make 4 small masks with 2 yards of material and 3 large masks with 2.25 yards of material. How much material would she need to make 20 small and 8 large masks for her class?
conversations.from: assistant
conversations.value: It takes 2 yards of material / 4 small masks = 0.5 yards of material per mask.
  It takes 2.25 yards of material / 3 large masks = 0.75 yards of material per mask.
  For the small masks, it will take 20 masks x 0.5 yards = 10 yards of material.
  For the large masks, it will take 8 masks x 0.75 yards = 6 yards of material.
  In all, it will take 10 yards + 6 yards = 16 yards of material.
