Final answer:
To determine the number of bathroom stalls in each of the 9 bathrooms for men and women, the total number of stalls required by city code is needed. Without that information, a final answer cannot be provided.
Step-by-step explanation:
The question revolves around the mathematical concept of division and allocation. To determine how many bathroom stalls need to be in each of the 9 bathrooms for both men and women to meet the city code, we require additional information, such as the total number of stalls that must be provided according to the city code. If such a code specifies that, for example, there must be 18 stalls in total, then each of the men's and women's bathrooms would need 1 stall each (18 total stalls / 2 genders / 9 bathrooms per gender). However, without the specific city code requirements on the total number of stalls, a definitive answer cannot be given.
The detail about the United States' value system regarding gender exclusive bathrooms isn't directly relevant to solving the problem, but it does provide context for why there's an equal number of bathrooms being allocated to each gender. Understanding this social norm may help us realize why the question is enforcing an equal number of bathrooms for men and women, emphasizing the equity in provision.
