Answer: Yes, she will finish before winter break is over.
Explanation:
Since we have given that
Number of days in winter break = 17
Number of pages she read in each day = 75
Number of pages in the Harry Potter series she wants to read = 759
Now, we'll use unitary method,
in 1 day , she read = 75 pages
in 17 days , she read is given by
and 759 pages is less than 1275 pages.
So, she will finish before winter break is over.
