Final answer:
The final selling price of the new battery-powered baby bouncy seat for ABC Company in Brazil cannot be calculated with the given information, as there are no details on markups and taxes provided.
Step-by-step explanation:
The question does not provide a clear rule for calculating the final selling price with the given production cost of $12 for a battery-powered baby bouncy seat. To determine the final selling price, we would typically need information on the markups, taxes, and any other additional costs that apply to the product in Brazil. However, such data is not provided in the question. Therefore, without specific percentages or amounts for markups and taxes, it is not possible to calculate the final selling price accurately.
