<p>lolcats, then they did it wrong. it used the word exactly</p>
<p>Hmm... I thought it said 35 people bought exactly 2.
ok, I checked back to previous posts, and basically people are disagreeing over two things: the total number of people and the number of people who bought 2 books.</p>
<p>Version 1: 160 people and 15 people w/ 2 books
Version 2: 150 people and 35 people w/ 2 books</p>
<p>^ i'm positive i got version 2</p>
<p>oh. fgh. good insight. i hope not</p>
<p>150 people at book fair, all bought at least 1. 35 bought 2. 5 bought 3.</p>
<p>150 + (35<em>2) + (5</em>3) - 35 - 5 = 195</p>
<p>thank you dutchess. i'm positive that i read the same thing, and i'm a very careful reader, too.</p>
<p>from the pattern i'm seeing (with the books problem and the reflection one), does anyone think its possible that there are different version of some problems? like problems with slight variations?</p>
<p>can some1 restate the question for the book thing again? i wanna do it again lol</p>
<p>zhaos, no need to show off that you can add. that is not what is in question</p>
<p>This is what I clearly remember being printed on the page...
Now if what tryptophan said is true (problems with slight variations), then this might not be what appeared on your test. So don't yell at me if you disagree.</p>
<p>There are 150 people in a bookstore. Everyone bought at least 1 book. 5 people bought 3 books and 35 bought exactly 2 books. How many total books were purchased?</p>
<p>...did anyone else get that?</p>
<p>was there an option for the I, II, III one as I and II only?
cuz if there was, i think i put that.</p>
<p>was it like
a. I only
b.II only
c.III only
d. I and II only
e. I and III only</p>
<p>or was I, II, and III an option</p>
<p>jake: that's how I solved the question, not showing how to add.</p>
<p>if i remember correctly, the 150 people bought 1-3 books. at least one but at most 3? </p>
<p>omg i'm gonna go crazy. i came back pretty confident (in math at least) and now i'm like, i have no idea...<em>prays</em></p>
<p>I got the 35 people bought 2 books one, Julie. Also, thank goodness tryptophan. I would hate to get a problem wrong for not READING.
Also, I think I put I and III. If we're discussing the same problem.</p>
<p>mine said</p>
<p>150 ppl
35 w/ 2books
5 w/ 3 books</p>
<p>and final answer 195</p>
<p>I. a>0
II. b>0
III. a>b</p>
<p>The answer was I and III because the slope (a) was positive and the y-intercept (b) was negative.</p>
<p>hopefully there are slight variations of the same problem, cause I, too, would hate to get the reflection one wrong for not reading. we'll just have to see when we get our scores....</p>
<p>so we should try to take a tally of: (1) who got only 1 reflection and (2) who got 35 people buying 2 books. this way, we can see if only a few read wrong or there really are variations in the problem to prevent cheating....</p>
<p>but how bout the actual responses. i know i put either I and II, or I and III.
was there a letter that had I and II is my question. sorry if it wasnt clear</p>
<p>ok i'm a little confused about the math reflection then...</p>
<p>I remember mine being like this but w/ B and A switched</p>
<p>A and B for me were switched (or that was how i remembered it)</p>
<p>duchess26200 and ColumbiaLover: Thanks! I was really worried when people said that 15 bought 2 books. I know there's no possible way I could misread 35 for 15.</p>
<p>Tomackze: No, that picture you provided is what I saw on my book. I just remember the question asking what point I would arrive at with only ONE reflection over line m.</p>
