Correct Answer: D

Rationale: To determine when Truck B becomes the better buy, we need to find the breakeven point where the total cost of owning and operating both trucks is the same. First, calculate the total cost for each truck by adding the initial cost to the cost of gasoline for the miles driven. For Truck A: $450 + ($4/mile * x miles), and for Truck B: $650 + ($4/mile * x miles). Set these two equations equal to each other and solve for x to find the breakeven point. By solving the equation, we find that Sally must drive 4375 miles for Truck B to be the better buy. The correct answer is D. Summary: A: 500 - Incorrect, too low of a mileage for Truck B to be the better buy. B: 7500 - Incorrect, too high of a mileage for Truck B to be the better buy. C: 1750 - Incorrect, not the correct mileage for Truck B to

Correct Answer: B

Rationale: To determine the total liquid in the pot, we add the volume of chicken broth (4 containers x 410ml) to the volume of water (1 liter = 1000ml). Total liquid = (4 x 410) + 1000 = 1640 + 1000 = 2640ml = 2.64 liters. Therefore, the correct answer is B. Choice A is incorrect as it miscalculates the total liquid. Choice C and D are significantly higher than the correct answer, indicating an error in calculation.

Correct Answer: B

Rationale: The correct answer is B: Group Z, Group Y, Group X. This is because Group Z has the largest number of doctors, followed by Group Y, then Group X. To determine this, we need to compare the order of each group's size. Group Z > Group Y > Group X in terms of the number of doctors. Choice A (Group X, Group Y, Group Z) is incorrect because it lists the groups in ascending order of doctor numbers, which is opposite to the correct order. Choice C (Group Z, Group X, Group Y) is incorrect as it incorrectly places Group X before Group Y. Choice D (Group Y, Group X, Group Z) is incorrect because it lists the groups in ascending order, which is the opposite of the correct order.

Correct Answer: B

Rationale: To find the square root of 1296, we look for a number that, when multiplied by itself, equals 1296. The square root of 1296 is 36 because 36 * 36 = 1296. Choice A (24) is incorrect since 24 * 24 is not equal to 1296. Choice C (31) and Choice D (12) are also incorrect as neither of them results in the square of 1296 when multiplied by themselves. Therefore, the correct answer is B (36).

Correct Answer: C

Rationale: To find the circumference of a circle, we use the formula C = 2πr, where r is the radius. Given that the radius is 3 inches, we substitute r = 3 into the formula: C = 2π(3) = 6π ≈ 18.85 inches. The best estimate among the choices is C: 18 inches, as it is closest to the actual calculated value of 18.85 inches. Choice A (12 inches) and B (16 inches) are too small, while choice D (24 inches) is too large compared to the calculated circumference.
