Just looking at the bookmarks sold, Roy earned $6 more than Ethan since he sold each bookmark $0.30 more than Ethan. Since both of them earn the same amount of money, this means that Ethan earn $6 more from selling of watches. Looking at the watches sold, Ethan sold them $0.50 more than Roy. Hence, in order to get $6 more from selling of watches, he need to sell 12 watches in total.
