Answer:
200 pounds 20% raisins 
800 pounds 5% raisins 
Step-by-step explanation:
Let number of 5% be x
and number of 20% be y
x + y = 1000
Also;
5% of x + 20-% of y = 8% of 1000 pounds 
= 0.05x + 0.2y = 80
From i , x = 1000-y
0.05(1000-y) + 0.2y = 80
50-0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
= 1000-200 = 800
 
        
                    
             
        
        
        
-2|x|<-8 
(-2|x|)/-2<-8/-2
|x|>4
x>4 or x>-4
