94	Top	In Question #13, change March to April every time it appears.
159	Top	In Question #161, The discussion of Statement 2 is incorrect.	If the change is -$50, then x = $2,650: impossible.The change must be +120.	If the change is +$120, then x = $2,820: impossible.The change must be -50.
158	Top	The explanation labeled 155. is realy the explanation for #174.

185	Bot	In the sample question at the bottom of the page,the second sentence accidentally uses the masculine pronoun HIS to refer to Alicia.	Her school, located on a corner, lies three blocks south and three blocks east of his home, also located on the corner.	Her school, located on a corner, lies three blocks south and three blocks east of her home, also located on the corner.
142	Bot	The final portion of the explanation for problem #9 is incorrect. The explanation incorrectly states the total time must be at least 145 minutes, and the sample schedule is incorrect.	The third waiting time must be at least 15 minutes, so the total time is at least the cumulative length of all four shows plus 35 minutes in waiting time, or 145 minutes. (One sample schedule that achieves this minimum: third show 10:45-11:30, fourth show 11:40-12:20, second show 12:30-1:00, first show 1:15-1:30.)	The third waiting time must be at least 15 minutes, so the total time is at least the cumulative length of all four shows plus 35 minutes in waiting time, or 165 minutes. (One sample schedule that achieves this minimum: 30 minute show 10:00-10:30, 40 minute show 10:40-11:20, 45 minute show 11:30-12:15, 15 minute show 12:30-12:45.)
181	Bot	Rates for supervised and unsupervised are switched.	Victor works at a rate of (1 job)/(t days) = 1/t job/day (supervised) and (1 job)/(t – 3 days) = 1/(t – 3) job/day (unsupervised).	Victor works at a rate of (1 job)/(t days) = 1/t job/day (unsupervised) and (1 job)/(t – 3 days) = 1/(t – 3) job/day (supervised).
182	Top	First step is described incorrectly.	First, divide through by the common denominator t(t – 3):	First, divide through by 36:
55	Mid	Replace the word whoe with whole.	Notice that if there are only two parts in the whoe,…	Notice that if there are only two parts in the whole,…
