Correct Answer: D

Rationale: To convert yards to inches, we need to know that 1 yard is equal to 36 inches. So, to find out how many inches are in 2 yards, we multiply 2 by 36, which equals 72 inches. Therefore, the correct answer is D. Choice A (36 inches) is the equivalent of 1 yard, not 2 yards. Choice B (48 inches) and C (60 inches) are incorrect conversions of 2 yards to inches.

Correct Answer: B

Rationale: To earn the same amount as Tim in 4 hours, Joe needs to work 4 hours and earn $30/hr x 4 hrs = $120. Joe earns $20/hr, so $120 ÷ $20/hr = 6 hours for Joe to earn the same as Tim. To find how many more hours Joe must work than Tim, we subtract the hours Tim works from Joe's hours: 6 hrs - 4 hrs = 2 hours. Therefore, the correct answer is B: 2 hours. Choices A, C, and D are incorrect because they do not accurately calculate the additional hours Joe needs to work compared to Tim to earn the same amount in 4 hours.

Correct Answer: B

Rationale: To solve the equation 4y - 6 = 14 for y: 1. Add 6 to both sides: 4y = 20 2. Divide by 4 to isolate y: y = 5 Therefore, the correct answer is B. Choice A is incorrect as 4 is not the solution. Choices C and D are also incorrect as they do not satisfy the equation when substituted back in.

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.
