## Marion rented a car for $18.00 Marion rented a car for$18.00 plus $0.10 per mile driven. Craig rented a car for$25.00 plus $0.05 per mile driven. If each drove d miles and each was charged exactly the same amount for the rental, then d equals (A) 100 (B) 120 (C) 135 (D) 140 (E) 150 Can some experts show the best way to solve this problem?

OA D we can easily solve this algebrically. but if give a little thinking we can do it orally as well. Craig is initially taking$7 more than Marion . For both to get the same amount Marion should compensate from the rate
per kilometer which he charges more than Craig, As Marion is charging $.05 per kilometer more than Craig he should drive 7/.05=140 kilometer for both to get the same amount . Hence option D ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 Top Reply Quote: Marion rented a car for$18.00 plus $0.10 per mile driven.

OA D Hi lheiannie07, Let's take a look at your question. Marion rented a car for$18.00 plus $0.10 per mile driven. If 'c' represents the amount charges and 'd' represents the miles driven, we can write: $$c=18+0.10d$$ Craig rented a car for$25.00 plus $0.05 per mile driven. We can write it as, $$c=25+0.05d$$ If each was charged exactly the same amount for the rental, then, $$18+0.10d=25+0.05d$$ $$0.10d-0.05d=25-18$$ $$0.05d=7$$ $$d=\frac{7}{0.05}=140$$ Therefore, Option D is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
