30	Bottom	Table at bottom of page, Row B. The numbers in columns B1, B2, and B3 are incorrect. They should be identical to the table at the top of the page: 35, 17.5 and 14 .	30, 15 and 12	35, 17.5 and 14
32	Bottom	The first sentence under the heading “How to Get Better at Working Backwards” references problems at the end of the chapter. Those problems actually exist online, in the Manhattan Prep Official Guide Problem Sets, available in the Student Center.
52	Top	The problem should state that the two begin running at the same time.		Nicky and Cristina begin running a race at the same time, though Nicky begins the race 36 meters ahead of Cristina.
55	Top	The correct answer is (B) 18 seconds. Delete the first paragraph from the explanation (Initially… starts running.) The final sentence should read “Nicky’s total time is 18 seconds.“	Initially, Nicky runs 36 meters at a rate of 3 meters per second. Therefore, Nicky runs for 36/3 = 12 seconds before Christina starts running. Nicky’s total time is 30 seconds: 12 seconds + 18 seconds = 30 seconds.	(B) 18 seconds Nicky’s total time is 18 seconds.
60	Middle	Under Step 2, the explanation says 6 hours, when it should say 6 miles	If you drive 2 miles an hour for 3 hours, then you'll travel 2 * 3 = 6 hours.	If you drive 2 miles an hour for 3 hours, then you'll travel 2 * 3 = 6 miles.
64	Bottom	Answer choice (B) should be 115.5%, NOT 116.5%

101	Bottom	The answer explanation for statement (2) should reflect the above correction to the statement (p.99).	Statement (2) says that the total revenue from ticket sales exceeded $1,750. Where did that number come from?	Statement (2) says that the total revenue from ticket sales exceeded $1,600. Where did that number come from?
101	Bottom	The answer explanation for statement (2) should reflect the above correction to the statement (p.99); the revenue from ticket sales exceeded $1,600. A typo is also corrected to reflect the correct lower bound of revenue.	If the revenue is greater than $1,750, it is closer to $2,500 than to $1,000…	If the revenue is greater than $1,600, it is closer to $2,500 than to $900…
119	Middle	In two places, the explanation should say that you're walking east, NOT west.	You need to hike west and cover that same distance back… Now, total: you'll hike 2.75 + 0.5 =3.25 kilometers east before you turn around…	You need to hike east and cover that same distance back… Now, total: you'll hike 2.75 + 0.5 =3.25 kilometers east before you turn around…
119	Bottom	The explanation should say that the answer is (C), NOT (D).		Now, total: you'll hike 2.75 + 0.5 = 3.25 kilometers west before you turn around. The correct answer is (C).
120	Top	The explanation should say that the answer is (C), NOT (D).		Therefore, you travel 2.75 + 3.75 = 6.5 kilometers total. Half of that, 3.25 kilometers, is spent hiking east. The correct answer is (C).
