Answer:
the answer is 3
Step-by-step explanation:
It can be inferred that the siblings of the autistic children in the study do not have autism.
Assuming display of computer is at 100%
So increase by 20% = 120 (20/100 *100)
then 20% of 120 is: 20/100 * 120 = 24
So the display is now 120-24 = 96
Hope this helps!
