The total number of books in Francisca's bookcase is 125.
Let the total number of books be B.
Given the following data:
The number of paperbacks = 40.
Percentage = 32%.
How to calculate the total number of books.
In this exercise, you're required to determine the total number of books in Francisca's bookcase if she has 40 paperbacks in her bookcase. Thus, we would write a mathematical expression for the word problem.
Translating the word problem into an algebraic expression, we have;
32/100 x T=40
0.32T=40
T=40/0.32
T = 125 books.
