D is the answer because if you calculate the answer correctly. that will be so.
        
                    
             
        
        
        
Ok,
The total is 63$:
= 63
It shows us one of the numbers for the equation, 13
+ 13 = 63
Two passes together plus the thirteen equals the total of 63$
the price of the pass is unknown, so we can use a variable to figure it out:
2x + 13 = 63
Now we solve
First subtract 13 from both sides:
2x + 13 - 13 = 63 - 13
Then divide both sides by 2:
2x ÷ 2 = 50 ÷ 2
Now we get our answer:
x = 25
 
        
                    
             
        
        
        
Sorry, I'm not sure.
I would suggest asking a trusted adult or teacher or redoing the lesson. Cheating isn't a good path: you will not do well in the future if you always search for answers on the internet.
 
        
             
        
        
        
You will get x as 56 and angle ABC as 51°
        
                    
             
        
        
        
I would say to add the 2 prices together and that would be your answer! 
So your answer is 261.81!
Hope this helps!
