Let's put them in order.
22, 23, 24, 30, 31, 33
Now find the middle of the numbers.
22, 23, 24 ║30, 31, 33
31-23
8
So the IQR is 8.
I believe the answer is -5
The answer isw c because when i first looked at it i was like its a then i soveled the problem out
6y+y=14
7y=14
Y=2
X=6y
X=2*6
X=12
One solution (-2,-3) is the answer
