Question 1116660
.
An event organizer is reserving rooms for two company-wide events. 
For the quarterly meeting this month, she reserved 3 conference rooms and 5 ballrooms, which can seat a total of 379 attendees. 
For safety training next month, she reserved 3 conference rooms and 4 ballrooms, which can seat 314 attendees. 
How many attendees can each room accommodate?
~~~~~~~~~~~~~~~~~~~


This problem is for mental solution.


<pre>
    1.  After reading the text, you should see that the difference of 379 - 314 = 65 is exactly the capacity of one ballroom.


    2.  Then the capacity of each conference room is one third of   314-4*65,  or  {{{(1/3)*(314-4*65)}}} = 18.


<U>Answer</U>.  18 persons for each conference room and  65 persons for each ballroom.
</pre>

Solved.
