Step-by-step explanation:
Selling price = Rs.80
Cost price = Rs.100
here, CP > SP 
Now...
Loss ( L ) = CP - SP 
 = RS.100 - 80
 = Rs.20 
Now...


= 20 %
 
        
             
        
        
        
Answer: 64 mph
We can see that after every hour, the car has traveled 64 miles. So the speed rate is 64 miles per hour.
        
                    
             
        
        
        
6(-3-4y)
-18-24y
(Multiply 6 by both numbers)
        
             
        
        
        
360°/60 = 6
25 x 6 = 150°
18 x 6 = 108°
15 x 6 = 90°
2 x 6 = 12°
then draw a pi chart with these angles
