A. $37.80 B.$38.50
C. $39.20 D.$39.50
E. $40.60 The OA is B He spent 40% (of the$35) on chicken feed.
40% of $35 =$14. So, he spent $14 on chicken feed. He got a 20% discount on the chicken feed. In other words, he paid 80% of the original price. So, let C = original price of chicken feed. We can write 80% of C =$14
Or we can write 0.8C = $14 Or, even better, (4/5)C =$14

To solve for C, we'll multiply both sides by 5/4 to get: C = (14)(5/4) = 17 1/2
So, the original price of the chicken feed = $17.5 Finally, if the farmer spent$14 (of the original $35) on chicken feed, then he spent the remaining$21 on goat feed (at no discount).

So, without the discount, the farmer would have paid $17.5 +$21 = $38.50 Answer: B Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use our video course along with Sign up for our free Question of the Day emails And check out all of our free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert Elite Legendary Member Joined 23 Jun 2013 Posted: 10018 messages Followed by: 494 members Upvotes: 2867 GMAT Score: 800 Hi All, This question is essentially about arithmetic and taking the proper notes. You can go about the math steps in a couple of different ways though - depending on how you 'see' this information. From the prompt, we know that the farmer spent$35 on feed.... 40% of his money on chicken feed.... and the rest on goat feed. This means that for every dollar he spent, $0.40 was spent on chicken feed and$0.60 was spent on goat feed. With a total of $35 spent, we can easily break down the two totals.... (.4)($35) = $14.00 on chicken feed The rest =$35 - $14 =$21 on goat feed

We were also told that the chicken feed was purchased at a 20% discount, which means that the farmer paid 80% of the regular price for that feed.

$14.00 = (.8)(Regular Price)$14/.8 = (Regular Price)
$140/8 = (Regular Price)$17.50 = (Regular Price)

We're asked what the price would have been if the farmer had bought both feeds at full price.... $21 +$17.50 = $38.50 Final Answer: B GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • 1 Hour Free BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Free Practice Test & Review How would you score if you took the GMAT Available with Beat the GMAT members only code • 5-Day Free Trial 5-day free, full-access trial TTP Quant Available with Beat the GMAT members only code • Magoosh Study with Magoosh GMAT prep Available with Beat the GMAT members only code • Free Veritas GMAT Class Experience Lesson 1 Live Free Available with Beat the GMAT members only code • 5 Day FREE Trial Study Smarter, Not Harder Available with Beat the GMAT members only code • Get 300+ Practice Questions 25 Video lessons and 6 Webinars for FREE Available with Beat the GMAT members only code • FREE GMAT Exam Know how you'd score today for$0
