Question

Peter is reading a 193-page book. he has read three pages more than one fourth of the number of pages he ahsn't read yet.
a. how many pages has he not read yet?
b. estimate how many days it will take peter to finish the book if he reads about 8 pages per day.

Answer 1

let the number he hasn't read yet be X
pages he has read = 3 + ¼x
so 3+¼x +x = 193
5/4x = 193-3 = 190
5x = 190×4 = 760
x= 760÷5 = 152

a. number of pages he hasn't read yet is 152
b if he reads 8 pages in 1 day
then he'll read 152 pages in 152/8 days = 19days
