Final answer:
To add flavor or heavy cream to an americano, based on the given scenario, you would have to add an extra $1 for each addition, which is similar to Netflix's 60% price hike situation in 2011 for customers wanting to maintain the same service level.
Step-by-step explanation:
If you are referring to the cost of adding flavor or heavy cream to an americano using the scenario from a coffee shop as a reference, it seems you need to add $1 for each addition to your coffee. Given the original coffee price of $2 and the additional costs of $1 for creamer and $1 for a sweetener, choosing both creamer and sweetener would indeed result in an extra cost of $1. This price structure is comparable to what Netflix customers experienced with the 60% price hike in 2011 where they also had to pay more to retain the same level of service. However, if your question pertains to a specific coffee shop's pricing policy, you would need to refer to their particular pricing for an accurate answer as each establishment has its own pricing strategy.
