Answer:
There are 90 pages in the book
Step-by-step explanation:
To solve this problem, we have to think as an equation
We are going to have to subtract from the total number of pages that we do not know, 40% of that same total and we will equal that with 54
40% = 40/100
t = total pages
t - (t * 40/100) = 54
t - 0.4t = 54
0.6t = 54
t = 54 / 0.6
t = 90
