How to calculate the price increase in the middle of the gym annual card?
Not really. After the gym handles the annual card, there is no need to calculate the midway price increase, because it is handled before the price increase. If the gym requires it, it is a breach of contract and cheating, and the deposit should be refunded. Year card: someone in the gym will apply for a year card, and the fee for doing it is 1800 yuan. There is no rule that you can go to the gym at will several times a year.
