Answer:
Step-by-step explanation:
<em>Let the number be x </em>
So,
=> The sum of number and 15 is x + 15
=> Three times will be 3(x+15)
<u>Given that</u> it equals 24
<u>So, the given condition is:</u>
3(x+15) = 24
<em>Resolving Parenthesis</em>
3x + 45 = 24
<em>Subtracting 45 to both sides</em>
3x = 24 - 45
3x = -21
<em>Dividing both sides by 3</em>
x = -7
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
