$from tip: 2 TOTAL revenue = x + 2 All of the money Jason receives from the renters including the tip is divided evenly among the five family members. So, Jason's share = (x+2)/5 Jason spends six dollars of his share leaving him with y dollars from the rental venture. So, (x+2)/5 - 6 = y Which of the following represents the amount, x, that Jason charged for the house rental? Solve the equation for x (x+2)/5 - 6 = y Add 6 to both sides to get: (x+2)/5 = y+6 Multiply both sides by 5 to get: x+2 = 5(y+6) Subtract 2 from both sides to get: x = 5(y+6) - 2 Simplify to get: x = 5y + 28 = C Cheers, Brent _________________ Brent Hanneson â€“ Founder of GMATPrepNow.com Use our video course along with Check out the online reviews of our course Come see 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 Brent@GMATPrepNow GMAT Instructor Joined 08 Dec 2008 Posted: 11274 messages Followed by: 1224 members Upvotes: 5254 GMAT Score: 770 Sat Dec 28, 2013 7:08 am sanju09 wrote: Jason collects x dollars by renting out his family's house while they are on vacation. He also receives a 2-dollar tip from the renters. Jason's family has five members including Jason, and all of the money Jason receives from the renters including the tip is divided evenly among the five family members. Jason spends six dollars of his share leaving him with y dollars from the rental venture. Which of the following represents the amount, x, that Jason charged for the house rental? (A) 5 â€¢ (y + 6) / 2 (B) ((y + 6) / 5) - 2 (C) 5y + 28 (D) 5y + 8 (E) 2 â€¢ (y + 6) / 5 Here's a solution using the input-output approach: Let's choose a nice value of x (rental price) that yields a nice y-value (Jason's remaining money). Let's say x = 28 If x =$28, then the TOTAL revenue (after the tip) = $30, which means Jason's share is$6
Once Jason spends $6, he has$0 remaining.
In other words, y = 0

So, when y = 0, x = 28
Now we'll check the answer choices to see which one yields an output of 28 when y = 0

(A) 5 â€¢ (y + 6) / 2 = 5 â€¢ (0 + 6) / 2 = 15 (NOPE)
(B) ((y + 6) / 5) - 2 = ((0 + 6) / 5) - 2 = negative something (NOPE)
(C) 5y + 28 = 5(0) + 28 = 28 BINGO!!
(D) 5y + 8 = 5(0) + 8 = 8 (NOPE)
(E) 2 â€¢ (y + 6) / 5 = 2 â€¢ (0 + 6) / 5 = 12/5 (NOPE)

Cheers,
Brent

Rent = x
Total Amount = x + 2
Share per person = (x+2)/5

(x+2)/5 - 6 = y
x + 2 = 5 (y+6)
x = 5(y+6) - 2
x = 5y + 28

Brent's second approach is wonderful. It makes life easy for those who are not very comfortable at Algebra. Hope Brent or Rahul pay their two bits at the following thread too:
