An online furniture store sells chairs for $200 each and tables for $650 each. Every day, the store can ship a maximum of 45 pieces of furniture and must sell no less than $16000 worth of chairs and tables. If x represents the number of tables sold and y represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
