Divide the new enrollment, 1260, by 1.05, which is 5% more than the enrollment last year. 1260 / 1.05 = 1200. ANSWER: C **NOTE** Work backwards: 1200 * 1.05 (which is 5% more than 100%) = 1260. This suggests that trial and error is a possible solution method to this problem, especially with a calculator. Since AB is parallel to DE, angle ABC and angle CDE are equal, being alternate interior angles. Likewise, angle BAC and CED are also equal. Thus, angle BAC = 60°. Because the 3 angles of a triangle sum to 180°, angle ACB = 80°. Because angle ACB and angle BCE are a linear pair, their sum is 180°. So, angle BCE = 100°. ANSWER: J Area of Triangle = ½ Base * Height 24 square units = ½ * 12 units * BD 24 = 6 * BD BD = 4 ANSWER: B Because the triangle is isosceles, the 2 other sides are equal. The other 2 sides are also equal to 8 * 2 + 3 = 19. The perimeter is then 8 + 19 + 19 = 46. ANSWER: J To solve for x, first add 10 to both sides of the equation: 3x = 34 Then divide both sides of the equation by 3: x = 34/3 Since that answer is not listed, 3 goes into 34 eleven times with a remainder of 1, or 11 and 1/3.
