Answer:
the book should have a total of 175 pages
Explanation:
Let the total number of pages in the book = X
Andre = 1/5 of X
Elena = 55 pages
Elena = 1/5 of x + 20 pages
55 pages = (1/5)x + 20 pages
55 - 20 = (1/5)x
35 = (1/5)x
x = 35 / (1/5)
x = 175
So the book has a total of 175 pages
Not 100% sure what the diagram means, but
Based on Lin's diagram, it seems like the book has 275 pages, which is not true.
