On November 20, 210 people in restaurant A used debit cards and did not get cashback, which represents 25% of the total visitors on that day. If the number of people who paid through cash and did not get a 2% cashback represents 35% of the total visitors, what is the difference between the total number of people who visited restaurant A and the number of people who paid through cash and did not get a 2% cashback?
