A store calls the original price of an item the X-level price. The store reduces the X-level price of an item by 30%, resulting in what the store calls the Y-level price of the item. The store then reduces the Y-level price of the item by 20%, resulting in what the store calls the Z-level price of the item. The Z-level price of the item is less than $ 49. Which of the following statements must be true?

Indicate all such statements.

A. The X-level price of the item is less than $ 86.00.

B. When the Z-level price of the item is subtracted from the Y-level price of the item, the result is less than $ 16.00.

C. The Y-level price of the item is a percent greater than the Z-level price of the item, where \(0 < a < 30\).
