Question

Peter is reading a 193-page book. He has read three pages more than one fourth of the number of pages he hasnt yet read. How many pages has he not yet read? Estimate how many days it will take Peter to finish the book if he reads about 8 pages per day.

Answer 1

Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have

n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days
