Peter is reading a 193-book. He has three pages more than one fourth of the number of pages he hasn't read.
a. How many pages has he not read?
b. Estimate how many days it will take Peter to finish the book if reads about 8 pages per day.
3+N/4=193-N N=pages not read
I assume you meant to write he has read three more ....
