I want to know the answer to the following question:
in 1880, how many dance halls were in Paris?
All the background I'm provided with is that "Bal-musette is a style of French music and dance that first became popular in Paris in the 1870s and 1880s; by 1880 Paris had some 150 dance halls in the working-class neighbourhoods of the city.". Is that enough to answer the question?
Answer: yes
