The prompt

Two illustrative online players in Europe each have GMV of EUR 1 billion a year. Player A is a marketplace: it takes a 12 percent commission and earns another 3 percent of GMV from sellers' advertising. Player B is first party and sells at a 20 percent gross margin. What is each player's revenue and gross profit, in EUR millions?
