conversations.value: Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?
  Give me a solution to this problem

conversations.value: We know Kevin bought a ticket and drinks, and this cost him 14 + 2 = 16 dollars.
  Since Kevin spent his entire budget, his food must have cost 20 – 16 = 4 dollars.
