The right answer is Option C.
Step-by-step explanation:
Hardcover books = 15
This represent 12% of total books.
Let,
x be the total number of books, therefore,
12% of x = 15
Dividing both sides by 0.12
As, 15 of them are hardcover books, the remaining will not be hardcovers;
Remaining books = Total books - hardcover books
Remaining books = 125 - 15 = 110
115 books are not hardcover.
The right answer is Option C.

X + y = 1.....x = 1 - y
x * y = 0.09
y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0
y - 0.9 = 0 x + y = 1
y = 0.9 x + 0.9 = 1
x = 0.1
y - 0.1 x + y = 1
y = 0.1 x + 0.1 = 1
x = 0.9
so ur 2 numbers are : 0.1 and 0.9
I think 4.12 if thats what your asking for.
