Which stаtement best describes the оverаll trend shоwn in Figure A?
In this essаy style exаm questiоn, yоu аre lоoking at a script designed for a streaming service platform. We have a base class called Subscription that handles a basic subscription plan. This basic plan just takes in a monthly fee of $10.00. Inside this class, there is a method that calculates the annual cost that by yearly total by multiplying that monthly fee by 12. There is also a __str__() method that returns a clean text description showing the label "Standard Subscription" along with its monthly price. Then, we have a Premium Subscription class, which inherits all the core features from the basic Subscription class but with additional functionality. It takes in an additional parameter called ultra_hd_fee because premium users get 4K ultra high definition streaming which costs them $5.00 per month. To support this, it has a total_monthly_cost() method that adds the base monthly fee and the Ultra HD fee together. It also overrides the calculate_annual_cost() method so that it correctly calculates the full yearly cost (combining both fees and multiplying by 12) and overrides the __str__() method to display the premium plan details. If you solve it correctly, then you should find 10 errors that need correcting. However, sometimes students create errors or code their fixes differently which result in fewer or possibly more errors. Your professor will grade this by copying and pasting your answer in an IDE and running the code so it is important to keep your indents in line with the indented code. Use the indent button shown in the toolbar for the Canvas essay question or hit the space bar 4 times for each level of indent that you need. To assist in your understanding, the results of running the code after all errors are fixed are shown below: sub1 str Standard Subscription ($10.00/mo) sub1 annual cost: 120.0 sub1 monthly fee: 10.0 premium1 str Premium Subscription ($15.00/mo with Ultra HD) premium1 monthly fee: 10.0 premium1 ultra hd fee: 5.0 premium1 total monthly cost: 15.0 premium1 total annual cost: 180.0 Rules & Guidelines: The imports, code indentation, and the # Test Area within main() at the bottom are 100% correct. Do not change anything in the test area. There are no basic syntax typos like missing colons (:) at the end of definitions or mismatched single ‘’ or double quotes “ “ or unpaired parenthesis (). The errors are strictly related to Object-Oriented Programming (OOP) logic and Python techniques. Look out for the misuse or absence of the self keyword, broken inheritance/super() calls, improper references to attribute and method names, and return statements. To answer: Copy and paste the code below into your essay question response box. Correct the 10 errors and leave a clear comment inline or directly above the line you fixed (e.g., # ERROR 1: Added self).
