Answer:
10 
Step-by-step explanation:
11, 13, 4, 9
In order to find the median we must first arrange the numbers in order (Least to greatest)
4, 9, 11, 13
If there is 2 numbers in the middle: the median is their average
If there is only one number in the middle, that number is the median.
Since there are two numbers (9 and 11) we have to take their average.
(9+11) / 2 = 20 / 2 = 10
The median is 10!

<u>Let's take this problem step-by-step</u>:
<u>Let's first set up some variables</u>:
- c: # of children
- a: # of adults
<u>Let's examine the information given:</u>
- Elevator can hold a maximum of 1500 pounds
           ⇒ average child is 75 pounds
           ⇒ average adult is 150 pounds
                  ⇒<em> therefore</em>: 
- Elevator can fit no more than 14 people
           ⇒ <em>therefore</em>: 
<u>Let's graph the equations</u>:
  
     ⇒ look at the image attached
<u>The point at which the two graphs intersect:</u>
   ⇒ <em>is the solution that represents the amount of children and adults and </em>
<em>       their combine weight</em>
<em />
<u><em>With the horizontal axis being the # of children and vertical axis being the # of adults</em></u><em>:</em>
<em>  ⇒ the </em><em>solution is 8 children and 6 adults</em>
<em></em>
<u>Answer: 8 children and 6 adults</u>
<u></u>
Hope that helped!
