Answer:
Carry
Step-by-step explanation:
Here let’s take any arbitrary value for the number of properties sold by Ellen.
Let the number of properties sold by Ellen he 10. We were told Andy sold twice of this, this means he sold 20 properties 
Bob sold 3 more than Ellen, meaning he sold 13.
Carry sold twice of Bob meaning he sold 26
Dora sold the addition of Bob and Ellen = 13 + 10 = 23
Carry sold 26 and this makes him the highest seller.
 
        
             
        
        
        
for one show it will be 23.1 minutes if you multiply 2.30 minutes by 3 and get 6.9 you subtract 6.9 from the 30 minutes and you should 23.1 minutes  
        
                    
             
        
        
        
On the first space write 0.24, on the second write 0.51, and on the last space write 0.9
