Question

John has read the first 114 pages of a novel. He has read 3 pages less than one-third of the novel.

Write an equation to describe the total number of pages p in the novel, and find the value of p.
Hellpppppp,

Answer 1

If John reads three more pages, he has read a third of the book. Therefore (114+3) = 1/3 * p. 117 = 1/3p Multiply both sides by 3 to isolate p. 351 = p. 351 pages are in the novel.
