Answer: it would cost a total of $194 
Step-by-step explanation:
A ticket to a movie theatre for a student is $7. The cost for an adult is $2 more than for a student. 
If student ticket costs $x, adult ticket would cost x + 2
This means that the cost for an adult is 
7 + 2 = $9
The cost of 13 adult tickets to the movie theatre would be 
13 × 9 = $117.
The cost of 11 student tickets to the movie theatre would be 
11 × 7 = $77
Total cost of 13 adult tickets and 11 student tickets would be 
117 + 77 = $194
 
        
             
        
        
        
Answer:
12
Step-by-step explanation:
You could actually list the numbers between (but not including) 45 and 58:
{46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57}.  I count 12 numbers here.
 
        
                    
             
        
        
        
It would be 1/2 times 1/3 to get 1/6 cups of butter.
