Correct answers: B, C, and D.
Reasoning:
- After Saturday: 45 − 21 = 24 copies.
- After the Monday shipment: 24 + 25 = 49 copies (so 25 represents the incoming shipment → B true).
- After Monday sales: 49 − 14 = 35 copies (so D true; E which says 26 is false).
- A is false because a sale is a decrease and should be represented by −14, not +14. C is true because −21 correctly represents the sale (decrease) of 21 books.
