Rationale: To find the product of 226 and 55.3, multiply the two numbers together: 226 * 55.3 = 12,541.8 The correct answer is B (12,541.8) because this is the accurate result of the multiplication. Choice A (12,500) is incorrect as it is a rounded-down approximation. Choice C (12,600) is incorrect as it is a rounded-up approximation. Choice D (12,450) is incorrect as it is a result of rounding down the actual product.

Correct Answer: C

Rationale: The Roman numeral XLIV represents the number 44. Here's the breakdown: - "XL" is 40 in Roman numerals. - Adding "IV" (4) to XL gives us 44. Therefore, the correct answer is C. Other choices are incorrect because: - A (34): This is incorrect as XL is 40, not 30. - B (54): XL is 40, not 50. - D (24): XL is 40, not 20.

Correct Answer: C

Rationale: The correct answer is C: 6 minutes. When the rat's speed is reduced by 50% due to the backpack, it will take twice as long to finish the maze. Therefore, if the rat initially finished the maze in 3 minutes, it will take 6 minutes with the reduced speed. Summary of other choices: A) 3 minutes - Incorrect because the rat's speed is reduced by 50%, so it will take longer than the initial 3 minutes. B) 4 minutes - Incorrect because the reduction in speed by 50% will result in a doubling of the time taken from the initial 3 minutes, making it 6 minutes. D) 1.5 minutes - Incorrect as the reduction in speed will cause the rat to take longer than the initial 3 minutes, not less time.

Correct Answer: A

Rationale: To determine the money left after shopping, subtract the total expenses ($101.85 + $21.90 + $42.66 = $166.41) from the initial cash amount ($200.00). Thus, $200.00 - $166.41 = $33.59 left. Choice A is correct. Choices B, C, and D are incorrect as they do not reflect the accurate remaining amount after subtracting the total expenses from the initial cash.

Correct Answer: B

Rationale: Step 1: Let Mr. Johnson's pay be x. Step 2: He gives half to family, so he has x/2 left. Step 3: He pays $250 to landlord, leaving him with x/2 - $250. Step 4: He has 3/7 of his pay left, so x/2 - $250 = 3x/7. Step 5: Solve for x: x/2 - $250 = 3x/7. Step 6: Simplify and solve to get x = $3,500. Therefore, the correct answer is B: $3,500. Summary: A: $3,600 - Incorrect. Does not satisfy the given conditions. C: $2,800 - Incorrect. Does not satisfy the given conditions. D: $1,750 - Incorrect. Does not satisfy the given conditions.
