Final answer:
Paula has read 70% of her book, which is 84 pages. By defining the total number of pages as x and setting up the equation 0.70x = 84, we find that the book has 120 pages in total.
Step-by-step explanation:
The question is asking us to find out the total number of pages in a book that Paula is reading for her English class. We know that Paula has read 70% of the total pages in a book she is reading for English class. Paula has read 84 pages. Let's define a variable x to represent the total number of pages in the book.
To write an equation based on this information, we take the information given and create the equation 0.70x = 84 because 70% of the total pages x equals the 84 pages that Paula has read. Now to find x, we solve the equation by dividing both sides by 0.70:
x = 84
0.70
x = 120
So, there are 120 pages in the book that Paula is reading.
Based on this calculation, it is highly unlikely that Paula will need to read a total of more than 1,050 pages as she has only read a portion of a much smaller book.
