Answer:

Step-by-step explanation:
We are given the following information in the question.
The open interval: (- 18,22).
Let p belong to the given interval then p represents all the values belonging to the given interval.
Open Interval: An open interval is a interval that does not include the end points.
Thus, we can write:

is the required inequality form required.
That is p can take values greater than -18 and smaller than 22.
 
        
             
        
        
        
There is 20% decrease in the number of members.
Step-by-step explanation:
Given, 
Members last year = Old value = 30 
Members this year = New year = 24 
Change = New value - Old value 
Change = 24 - 30 
Change = -6 
The negative sign indicates the decrease.
Decrease percent = 
Decrease percent = 
Decrease percent = 
Decrease percent = 20% 
There is 20% decrease in the number of members.
