Final answer:
If you add flavor to your tea, it will cost an additional $1.
Step-by-step explanation:
In this scenario, the pricing has changed from $3 for a cup of coffee to $2 for coffee, $1 for creamer, and $1 for sweetener. If you pay $3, you can choose between creamer and sweetener. If you want both, you need to pay an extra $1.
This means that if you add flavor to your tea, it will cost you an additional $1. Therefore, the correct answer is D) 25 cents, as none of the given options represents the added cost correctly.
