Answer:
A shows the correct set of equation.
Late books = 12/100 x 462
Total fines = late books/4.25
Step-by-step explanation:
Total number of books issued = 462
Fine on late books = $4.25 per book
12% of the issued books are late returned.
So, the number of the books that are returned late here= 12% of 462
Late books =
Also, Since fine on each late book = $4.62
The fine on late books = Total number of late books x ($4. 62)
So, A. is the correct option
