Example text

Column B The sum of two consecutive integers is 83. 23 less than three times the smaller integer 16 more than two times the greater integer 250. 15 in quarters and dimes. the number of quarters the number of dimes 40 501 Quantitative Comparison Questions Answer Explanations The following explanations show one way in which each problem can be solved. You may have another method for solving these problems. 126. b. The number 1 to any power is 1; 23 is 2 × 2 × 2 which is 8; 1 + 8 = 9. The quantity 25, in column B, is greater.

140. a. The quantity (x + 3)2 = (x + 3)(x + 3). By the distributive property, this equals x2 + 3x + 3x + 9 = x2 + 6x + 9. You can subtract x2 and 9 from each column and you are left with 6x in column A and zero in column B. Since x > 0, column A is greater. 42 501 Quantitative Comparison Questions 141. b. The given equation is a quadratic in the form ax2 + bx + c, where a, b, and c are real numbers. The minimum y value of the function is the y value at the vertex. The x-coordinate of the −b −6 vertex is given by the formula ᎏ2ᎏa = ᎏ2ᎏ = −3.
