25. (B). This question is an Analyze the Argument Structure question; the best approach is to identify the conclusion, and then check each boldface portion of the question for how it relates to the conclusion, and eliminate incorrect answer choices on that basis. Here, the second boldface is the conclusion of the argument, as highlighted by the use of the signal word “Therefore.” (A) The first boldface is not an assumption, as assumptions are, by definition, unstated. Also, the second boldface does not just describe the argument’s recommended position, it is itself the conclusion of the argument. (B) CORRECT. The first boldface is a consideration that helps explain why companies charge as much as possible for new designs. The second boldface presents a different strategy endorsed by the argument, of charging less than the greatest possible price to maximize profit. (C) The first boldface is not an assumption, as assumptions are, by definition, unstated. The second boldface is not the strategy referenced in the first boldface, as this answer choice suggests. (D) The first boldface does not demonstrate that the strategy of selling for the greatest price will not apply, but instead supports it. Also, the second boldface is the argument’s conclusion itself, not a factor in support of it. (E) The description of the first boldface is accurate; however, the second boldface is not a factor against the strategy of maximizing profits by charging the greatest possible price, but an alternative strategy altogether. |

1044 | Bottom | #47 answer and explanation | 47. 36.6. To calculate first find the squared differences between the average and the terms. For example, the difference between the average, 4, and the first term, -1, is 5. 52 = 25. Do this for all four terms. | 47. 18.2. To calculate, first find the squared differences between the average and each of the terms. For example, there is a difference of 4 between the average, which is 3, and the first term, which is -1.

1044 | Bottom | #47 explanation | Add all of these terms together: 25 + 16 + 625 + 676 = 1,342. | Add all of these terms together: 16 + 1+ 729 + 576 = 1,322. | |
1045 | Top | #47 explanation | Take the square root (use the calculator!): Square root of 1342 = 36.633. | Using the calculator, divide by the number of terms to get the variance: 1,322/4 = 330.5.
