A fitness center surveyed its members about which classes they attend. Use the Venn diagram to answer the following questions. (B) How many total members were surveyed?

Welcome back. For this problem, we have a fitness center that surveyed its members about which classes they attend. We'd like to use the Venn diagram to answer the following question. How many total members were surveyed? Now, as a reminder, every member who was surveyed will appear in one region in our Venn diagram. So to get the total number of people in the survey, we just need to add together each of our region totals. This includes the 54 people that just take yoga. The 31 people who just take Zumba, the 34 people who take yoga and Zumba, and the 31 people that are not in either circle, so they're in the survey, but they don't take either yoga or Zumba. When we add together these region totals, we end up getting 150. So we know that 150 total members were surveyed. Great work.
