Question 1162030
.


            From your post,  I see that you love correctness and precise treatment of Math problems.


            It is  VERY  GOOD  and I like it  (!)


            But let me tell you that you  INCORRECTLY  use the word  (the term)  "average"  in your post.


            So,  I edited your post to make it smooth.  My editing is below.



<pre>
    A local playhouse has 200 seats. Records of ticket sales show that at $24 per ticket, 
    they {{{highlight(cross(average))}}} <U>sold</U> 180 seats {{{highlight(cross(sold))}}}, <U>in average</U>; 
    when tickets are priced at $36, they sold 160 seats, and at $45, only {{{highlight(cross(an_average_of))}}} 145 tickets were sold, <U>in average</U>. 


    Make a TABLE to represent this data, then write a linear equation that represents this situation (using point-slope formula).
    Based on the linear equation, how much per ticket should the playhouse charge in order to sell all 200 tickets?
