The answer is 358 to the question
In the problem above, let x be the cost of ticket for adults. Based on the description stated by the clerk, each child's ticket costs x - 11.
The total cost of the ticket is $174.45 and may be used to get the value of x. The equation is,
2x + 3(x - 11) = 174.45
Solving x in the equation gives x = 41.49 and x -11 = 30.49. Thus, each adult's ticket cost $41.49 and child's ticket costs $30.49.
