ACT is incorrect? (June 2012 QAS Math)

Test Preparation ACT Preparation

<p>So I just got in my question/answer service paper and reviewed the questions I missed. I don’t understand why these two are incorrect. My family and friends have tried them as well and get the same answers as me, so I’m considering e-mailing ACT. I wanted your opinions first though:</p>

<p>34) Jim took his large dog to Pretty Pooches for a haircut 3 times. Jim paid full price for the first 2 haircuts, and had a coupon for the 3rd haircut, giving him a 15% discount on the 3rd haircut. How much did Jim pay for the 3 haircuts? (Table on page shows that price for a large dog haircut is $55)</p>

<p>f. $99.75
g. $118.75
h. $137.50
j $150.00
k. $156.75</p>

<p>60) If abs(x) = -x, which of the following statements MUST be true?</p>

<p>f. x ≤ 0
g. x ≥ 0
h. x = 0
j. x ≠ 0
k. x is not a real number</p>

<p>34) Everyone I’ve asked comes up with k. $156.75 and it seems impossible for ACT’s answer (f. $99.75) to be correct, as the price of the first two haircuts alone would be 55+55=110, which is already greater than answer f.</p>

<p>60) ACT claims the answer is h. x = 0, but why not f. x ≤ 0? 0 is a definite possible value of x, because abs(0) = 0 and -0 = 0, therefore abs(0) = -0. However, why not -1? abs(-1) = 1 and -(-1) = 1, so why is answer f. incorrect?</p>

<p>There probably is a reasonable explanation that I’m just missing, but what are your solutions? Sorry if this seems redundant, but I’ve done the math, and if these questions are correct, my math subscore goes up 2 points and in turn raises my composite by 1, which is enough to bring me to my goal score. Especially since I want to major in math/science/engineering, I feel it is worth it to ask these questions of this board. Thoughts anyone? Thank you!</p>

<p>34) $156.75 is correct (2.85 * 55) presuming you read the table correctly.</p>

<p>60) Yeah, H is not always correct. |x| = x iff x ≥ 0, and |x| = -x iff x ≤ 0. F is correct.</p>

<p>You should definitely contact ACT on this. They’re not supposed to be making mistakes like that…you think they’d actually take some time to proofread their questions.</p>

<p>Thank you! I’ll send it right now. I’ve just been waiting for someone else to confirm this with me!</p>

4

<p>No problem…yeah, I got a 36 on ACT math but I’ve never seen a mistake on their part. What a shame…</p>

<p>I don’t know about you, but my packet says F is in fact the correct answer on 60.</p>

7

<p>Hm. Well then maybe it was just an error in printing on mine? Though I doubt that would happen often. Let’s hope it was just that.</p>

<p>34 is definitely k and I actually took my ACT in June 2012 as well and I hope they made this mistake with my test as well. I ordered my question and answers and so they should be here soon but if they made that mistake with everyone and not just you, I hope they increase our scores for us. Please send that mistake in to ACT so that our scores can increase!! Thanks!</p>

<p>34 is K according to the answer key… Maybe you are looking at the wrong column?</p>

<p>I got my QAS and i checked #34 and it is K for me. So it is right for me. There is no error in my score. I have test 70C.</p>
