Correct answer is C - 13500.

Total profit per weekday = $600 X 3 (shifts)=$1800
Total profit per week (apart from Saturday & Sunday) = $1800 X 5 =$9000

Total profit per shift on weekends = $600 X 125/100 =$750

Total profit on weekends = $750 X 3 (shifts) X 2 (Saturday, Sunday) =$4500.

Hence the answer is - $4500 +$9000 = $13,500. (C) Intern Joined: 26 Feb 2011 Posts: 34 Re: A slot machine in a Las Vegas casino has an average profit of$600 for [#permalink]

A slot machine in a Las Vegas casino has an average profit of $600 for each 8-hour shift for the five days Sunday through Thursday, inclusive. If the average per-shift profit on Friday and Saturday is 25% greater than on the other days of the week and the slot machine is in operation every hour of every day, what is the total weekly profit that the casino makes from the slot machine? a - 4500 b - 9000 c - 13,500 d - 15,500 e - 27,000 The wrinkle in this question: profit is given in shifts of 8 hours, but the question asks for total profit where the machines operate 24 hours a day. Total weekly profit will be: 1) per-shift profit * 3 (to get 24 hours) * 5 (days) for Sunday to Thursday, plus 2) per-shift profit * 3 * 2(days) for Friday and Saturday Every solution posted uses #s 1 and 2. Every solution is a condensed version of the explanation below, which I'm posting because the stats seem unusually skewed for this question. 1. Sunday through Thursday: From Sun to Thurs, the average profit for an 8-hour shift is$600.

But to calculate total profit of machines working all day, every day, we need total profit for each day of 24 hours:

$$\frac{600}{8hrs}$$ = $$\frac{x}{24hrs}$$ -->

8 is multiplied by 3 to get 24. Multiply 600 by 3 to get the numerator x

x = $1,800 per day for the five days Sunday through Thursday Su - Th total profit =$1,800 * 5 = $9,000 2. Friday and Saturday: average per-shift profit is 25 percent greater than on the other days 1.25 *$600 = $750 per 8-hour shift $$\frac{750}{8hrs}$$ = $$\frac{x}{24hrs}$$ --> ($ 750 * 3 to get x)

x = $2,250 per day * 2 days =$4,500 total for Fri and Sat

Total weekly profit is $9,000 +$4,500 = $13,500 Answer C _________________ In the depths of winter, I finally learned that within me there lay an invincible summer. -- Albert Camus, "Return to Tipasa" Target Test Prep Representative Status: Founder & CEO Affiliations: Target Test Prep Joined: 14 Oct 2015 Posts: 2738 Location: United States (CA) Re: A slot machine in a Las Vegas casino has an average profit of$600 for [#permalink]

Therefore, the casino makes a total of: 600 x 5 x 3 + 1.25(600) x 2 x 3 600 x 15 + 750 x 6 9000 + 4500 = 13500 Answer: C _________________ Scott Woodbury-Stewart Founder and CEO GMAT Quant Self-Study Course 500+ lessons 3000+ practice problems 800+ HD solutions Re: A slot machine in a Las Vegas casino has an average profit of$600 for   [#permalink] 29 Aug 2017, 17:19
