Katie has read 32% of a book. if she has read 80 pages, how many more pages does katie have left to read?

Step-by-step explanation:

x=total number of pages.

1)we calculate the total number of pages.

32% of x =80

(32/100)x=80

x=(80*100)/32

x=250.

2) we calculate the number of pages don´t read.

number of pages don´t read=250-80=170  

170 pages.

answer: -2+√x,-2-√x
