How many pages are there in the book
Sophia is reading a book. On the first day, she reads 1/5 of the pages plus 12 more. On the second day, she reads 1/4 of the remaining pages plus 15 pages. On the third day, she reads 1/3 of the remaining pages plus 18 pages. After this, she has 1/4 of the book left to read. How many pages are there in the book?
Distribute the numbers inside the parentheses:
ReplyDelete3x - 12 + 5 = 2x + 12
Simplify both sides:
3x-7=2x+12
Subtract 2x from both sides:
x - 7 = 12
Add 7 to both sides:
x=19
