Answer:
edit: 92-17=75
Step-by-step explanation:
when using range you subtract the highest number with the lowest
 
        
             
        
        
        
Let us denote the number of tiles by 

.
In the first store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
In the second store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
For the cost to be the same at both stores, it means (measured in $)                                           

Moving 

 over to the left hand side and changing signs:                                            
 
                                             
                                             
                                            
 tiles
Let's check. If he buys 60 tiles in the first store, he spends:
                              $0.79×60 + $24 = $47.40 + $24 = $71.40
If he buys 60 tiles in the second store, he spends:
                                               $1.19×60 = $71.40
∴
 Darin needs to buy 60 tiles for the cost to be the same at both stores.

Hello! So, 25% of the 60 tables seat two people. To find this number, multiply 60 by 25%. 60 * 25% (0.25) is 15. 15 of them seat 2 people and 15 * 2 is 30.The other 45 tables seat 4 people. When you multiply both number, you get 180. Now, let's add the numbers together. 180 + 30 is 210. There are 210 seats in the restaurant. The answer is C: 210.
