Write JavaScript/jQuery code that is invoked when the calculate price button is clicked, which calculates the price of tickets. Your code must be well documented with meaningful variable names. The logic is as follows:

A single pass costs 60 AED, a monthly pass costs 80 AED, and a season costs 100 AED.

Apply Discount (20% or 50%)

Consider the quantity when you are calculating the final price, for instance, if the user chooses 2, then it will be multiplied by the ticket price.
