Project cost of Jiaxing Water Park

Adult ticket 90, child ticket 70. There is no charge for the project, but 10 yuan needs to rent a locker, and 30 yuan needs to rent a raft ring for half an hour, with each additional half an hour 10 yuan. There are children's paradise * (adults are not allowed to enter), three-color slides, high-speed slides, sled slides, flying saucers, and then there are spa pools, surfing pools (the most beautiful one in my opinion), circulating rivers (rafts can only be rented for fun) and water discos. That's all. Although we don't charge money, we still charge money in different ways. Otherwise, how can it be recovered from his tens of millions of investments? Oh, a bottle of coke in 5 yuan.

If you want to play, you'd better bring your own swimsuit (more expensive) and drinks, and you'd better not spend it in it.
