Question 1169082
<br>
22 chairs at $150 each means $3300.<br>
That leaves $7200-$3300 = $3900 for the minimum cost of tables that must be sold.<br>
$3900 at $550 each for the tables means at least 6 tables.<br>
With 22 chairs sold, the maximum number of tables sold is 32-22 = 10.<br>
So the number of tables that can be sold to meet all the requirements is 6 to 10, inclusive.<br>
