Accepted Solution

A:
Answer:All possible values for the number of tables that the store must sell in order to meet the requirements are 9, 10, 11, 12, 13.Step-by-step explanation:Let x be the number of chairs sold and y be the number of tables sold.Chairs are sold for $50 each, then x chairs cost $50x.Tables are sold for $250 each, then y tables cost $250y.In total, x chairs and y tables cost $(50x+250y).Every day, the store can ship no more than 36 pieces, then[tex]x+y\le 36[/tex]Every day, the store must sell at least $3,400 worth of chairs and tables, then[tex]50x+250y\ge 3,400[/tex]If 23 chairs were sold, then x = 23. Substitute it into the inequalities:[tex]23+y\le 36\Rightarrow y\le 13\\ \\50\cdot 23+250y\ge 3,400\Rightarrow 250y \ge 2,250,\ \ \ y\ge 9[/tex]Thus [tex]9\le y\le 13[/tex]This means all possible values for the number of tables that the store must sell in order to meet the requirements are 9, 10, 11, 12, 13.
