Roxanne read a book. On monday she read 120 pages of the book. On tuesday she read 15%, wednesday 10% and the rest 60 pages on thursday. Calculate the total number of pages of the book.
= 120+(15 x 100 + 10 x 100) + 60
= 120 + 1500 + 1000 + 60
= 2 680 pages
total of pages ---- x
120 + .15x + .1x + 60 = x
solve for x

To calculate the total number of pages in the book, we need to add up the number of pages Roxanne read on each day.
On Monday, Roxanne read 120 pages.
On Tuesday, she read 15% of the total book pages. To convert this percentage to the actual number of pages, we need to find what 15% represents in terms of the total number of pages.
Let's assign 'x' as the total number of pages in the book. Therefore, 15% of x can be represented as (15/100)*x, which simplifies to 0.15x. This means Roxanne read 0.15x pages on Tuesday.
On Wednesday, she read 10% of the total book pages. Using a similar process as before, 10% of x can be represented as (10/100)*x, which simplifies to 0.1x. This means Roxanne read 0.1x pages on Wednesday.
Finally, on Thursday, she read the remaining 60 pages.
Now, to find the total number of pages, we add up the number of pages read on each day:
Total pages = Monday pages + Tuesday pages + Wednesday pages + Thursday pages
Total pages = 120 + 0.15x + 0.1x + 60
Simplifying further:
Total pages = 120 + 0.25x + 60
Total pages = 180 + 0.25x
Therefore, the total number of pages in the book is 180 + 0.25x.
