- A.The library made an error because the calculated fee is $4.75.
- B.The library made an error because the calculated fee is $5.25.
- C.The fee is correct because the student paid exactly the calculated amount.
- D.The student must have returned another book late as well.
Kunci jawaban & pembahasan
Jawaban: The library made an error because the calculated fee is $4.75.
The fee should be 5×$0.25 + 7×$0.50 = $1.25 + $3.50 = $4.75, so the library overcharged by $0.25. Thus, an error occurred.
