  The bar graph above shows the number of people in attendance at each of the four meetings of the Maple Street Block Association that were held in2011. Only members of the Block Association can attend the meetings, and no members joined or left the Block Association during2011. Based on the bar graph, what is the least number of members the Maple Street Block Association could have had in2011?

  (A)61

  (B)65

  (C)67

  (D)72

  (E)268

  The correct answer is D

  Explanation

  The highest attendance was at the spring2011meeting, which had72people attending. Since only members can attend the meetings, these72people must have been members of the Maple Street Block Association; thus, there must have been at least72members of the Block Association. If the65,61and70people who attended the winter, summer and autumn meetings, respectively, were all among the72people who attended the spring meeting, then the Block Association could have had as few as72members in all. Therefore, based on the bar graph, the least number of members the Maple Street Block Association could have had in2011is72.

  If24 over 15 = 4 over n, what is the value of4 times n?

  (A) 6

  (B) 10

  (C) 12

  (D) 30

  (E) 60

  The correct answer is B

  Explanation

  Multiplying both sides of the equation24 over 15 = 4 over nby15 times ngives(15 times n) times (24 over 15) = (15 times n) times (4 over n), which simplifies to24 times n = (15) (4) = 60. Dividing both sides of the equation24 times n = 60by6gives(24 times n) over 6 = 60 over 6, and so4 times n = 10.

  While programming the answer key for the Official SAT Question of the Day application on collegeboard.org, the answer to the November 23rd question was incorrectly entered into the application "A (6)" instead of "B (10)." While the question, hint, and answer explanation were displayed correctly, anyone who entered the correct answer "B (10)" received a message indicating that response was incorrect. We have resolved the issue and apologize for any confusion this may have caused.
