Final answer:
The question about the number of scoops for extra sweet coffee is not directly answered by the provided information, but suggests adding more sweetener scoops based on customer preference. It compares measurement in coffee making to taking medical measurements at a doctor's office.
Step-by-step explanation:
The question about how many scoops to use when someone orders their coffee extra sweet does not have a specific answer provided in the given reference information. Typically, the number of scoops for making coffee sweeter would depend on personal preference or the standard practice of the coffee shop.
However, if the standard recipe is 3 scoops of coffee for 4 cups of water, and someone requests an extra sweet cup of coffee, you could add more scoops of sweetener based on how much sweeter they want it compared to the standard recipe. Since this is a matter of measurement, like when a nurse measures your temperature or blood pressure, the increase should be proportional and according to taste.
Referencing the cost scenario, if a coffee shop starts charging separately for coffee, creamer, and sweetener, customers would have to decide how much sweetener to pay for based on their preference for sweetness and their willingness to pay additional charges.
