conversations.value: I'm stuck on this math problem: Sarah is planning to do some baking. She buys 5 pounds of rye flour, 10 pounds of whole-wheat bread flour, and 3 pounds of chickpea flour. Sarah already had 2 pounds of whole-wheat pastry flour at home. How many pounds of flour does she now have?
  Can you help?
