conversations.value: I would love to understand how to solve this problem: For breakfast, Anna bought a bagel for $0.95 and a glass of orange juice for $0.85. At lunch, Anna spent $4.65 on a sandwich and $1.15 on a carton of milk. How much more money did Anna spend on lunch than on breakfast?
  Can you explain?

conversations.value: The total cost of breakfast is $0.95 + $0.85 = $1.80.
  The total cost of lunch is $4.65 + $1.15 = $5.80.
  Anna spent $5.80 − $1.80 = $4 more on lunch than breakfast.
