You would find this by doing 250 times 20% which is .2 and you would get 50 so you would add 250 plus 50 and get 300.
The answer is $300
        
                    
             
        
        
        
Answer:11.7
Step-by-step explanation:
 
        
             
        
        
        
The sample mean is the sum of the sample values divided by the number of them:
  (7 +7 +10 +6 +9 +6 +8 +7.5 +8.5 +8)/10 = 77/10 = 7.7
The sample mean is 7.7.
        
                    
             
        
        
        
Each level has 4 castles to conquered. Jackson completed 6.
Let x be the number of remaining levels and y is the total number of castles to defeat
For every x, there are 4 castles to conquered, 4x represents number of remaining levels and corresponding castles.
Since he has already conquered 6 levels 4(6) = 24 so
y=4x+24, A.
