An online furniture store sells chairs for $150 each and tables for $550 each. Every day, the store can ship at most 32 pieces of furniture and must sell no less than $7200 worth of chairs and tables. If 22 chairs were sold, determine all possible values for the number of tables that the store must sell in order to meet the requirements. Your answer should be a comma-separated list of values. If there are no possible solutions, submit an empty answer.
