## Vacation Books

Math brain teasers require computations to solve.

 Puzzle ID: #31530 Fun: (2.17) Difficulty: (1.4) Category: Math Submitted By: holly1447591

Morgan came home from her vacation at Grandma's with 6 books. While she was away she purchased 3 books at the book store and got 1 book as a gift. During her stay at Grandma's, she also gave her cousin the 2 books that she finished.

How many books did she take with her when she left for her trip?

Morgan started with 4 books.

This is one way to work backwards:

Morgan returned with 6 books.

She gave away 2 of the books that she had.
So add those two books back to her total.
6 + 2 = 8

So subtract that book from her total.
8 - 1 = 7

She bought 3 books that she had not brought with her.
So subtract those books from her total.
7 - 3 = 4

She must have left for vacation with 4 books.

 danielzerman Jul 04, 2006 great one i loved it Nellem Jul 04, 2006 I like this type of short and snappy math teaser - and an easy one is a nice change! stil Jul 04, 2006 good word problem - so-so teaser Cogmatic Jul 06, 2006 I wouldn't really call this a teaser. It's more of a basic grade school word problem. In other words, this was a really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, easy. You're the one in the middle. Everyone else and I are the ones that are laughing. The truth hurts. Deal with it. barrom Jul 09, 2006 What Cogmatic said was cruel, and should have been removed from this site. Although that I must admit that this teaser was incredibly easy, it was fun - I was glad not to see just tedious sums which are only applicable to a small amount of viewers (because they are based on things that only people from a certain country/religion can understand). Even though challenges are usually fun, this was one which I think will be a hit with younger viewers. Good effort! mmmcla01 Jul 18, 2006 Cogmatic-why do you have to be so mean? There are a lot easy teasers...that doesn't make them any less fun and enjoyable! And why bother even posting a comment just to hurt someone's feelings? It is a MAJOR waste of time! Although this teaser was very simple, it ws fun...it's nice to have something easy once in a while so you don't have to totally drive yourself crazy! Good Job!! mmmcla01 Jul 18, 2006 Oops... mmmcla01 Jul 18, 2006 (was)...not ws!! 4demo Jul 18, 2006 A fun teaser, although it was easy! javaguru Jan 28, 2009 While I don't agree with how he said it, Cogmatic's assessment of the "teaser" is spot-on. This is a word problem you'd expect to encounter in kindergarten or first grade. That it has a 2.25 fun and 1.44 difficulty rating is a mockery of the rating system, which admittedly already mostly a popularity contest for the person who submitted the teaser and not a useful rating system.
