Answer:
Didn't know how far I was needed to go, but I hope something there helps you.
Step-by-step explanation:
9p - 3p +2 = 0
6p +2 = 0
6p = -2
p = -2/6
p = -1/3
Ok, so 120 pages plus the 60% of the book she has left to read will give the total number of pages.
That means that 120 pages is 40% of the book.
Make a proportion
120/40% = x/60%
72 = .4 x
x = 180 pages
