So far, Jesse has read 10 + 15 + 27 + 12 + 19 = <<10+15+27+12+19=83>>83 pages.

That's 1/3 of the book, so the remainder of the book is twice as many pages, or 2 * 83 = 166 pages.

Jesse is desperately trying to finish a book for a school book report due on Monday so he can play this weekend. Friday afternoon, he read the first 5 chapters, which were 10, 15, 27, 12, and 19 pages, respectively, before taking a break. To his dismay, he found that he was only 1/3 of the way through the book. How many pages does he still have to read?
