Answer:
<em>There are 1700 books in the library.</em>
Step-by-step explanation:
<em>If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.</em>
If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.
If 1% is 17 books, then 17*100=100% of books.
There are 1700 books in the library.
The total cost that will be paid by the family will be RM(15x - y).
<h3>How to calculate the cost?</h3>
The entrance fee to a circus for a child is RM(3x-y).
The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.
Therefore, the cost for 2 adults and three children will be:
= 2(3x + y) + 3(3x - y)
= 6x + 2y + 9x- 3y
= 15x - y
