A graphing calculator or spreadsheet program can do this for you. Below is a plot from the Desmos on-line graphing calculator.
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
I believe the answer would be 6 because 7x2=14 so 3 cantaloupes x 2= 6
Answer: B
