Final answer:
Without further context or specific details on the stock price changes, it's not possible to identify the correct final stock price from the options provided. The information given includes historical stock price data of a company similar to Netflix but cannot be used to answer the student's question.
Step-by-step explanation:
The student is asking for the final stock price after a price change. However, from the information given, it's not clear what the starting price was or what specific changes occurred either through increases or decreases to be able to provide an accurate final stock price from the provided options (A, B, C, D).
To calculate a final stock price after a series of changes, one would typically use the initial price and apply each change consecutively to find the final price. For example, if we knew the initial price and the percentage changes, we could multiply the initial price by each change (expressed as a decimal in case of a percentage) to determine the new price after each change.
However, the text provided recounts the historical stock price of a company resembling Netflix, where the price went from around $33.60 to below $7.80 after the first year of a price increase event, eventually reaching $123 by the end of 2016, and just over $600 by the end of 2021 with subscriber increases over time. These details cannot directly answer the student's question without additional context or the starting stock price and changes in question.
