Answer:
78
Step-by-step explanation:
The total you are buying is 112 pounds.  The can you have picked up is 34 pounds; this leaves
112-34 = 78 pounds remaining.
 
        
                    
             
        
        
        
<span>194 = 1/2x + 2(x - 8)
194 = 1/2x + 2x - 16 = 5/2x - 16
5/2x = 194 + 16 = 210
5x = 210 x 2 = 420
x = 420/5 = 84
Therefore, the regular price of a child's ticket is $84 - $8 = $76.
