Answer:
The answer is: The excise tax on cola beverages is $2 per case.
Step-by-step explanation:
Excise taxes are taxes levied on certain goods or services.
In this case the price of cola beverages is $4 per case, since excise taxes are included in the price of the product, then the excise tax on cola beverages = price paid by consumers - price received by producers = $4 - $2 = $2
