Correct Answer: D

Rationale: To find the number of nights Sarah needs to read 140 pages, we first calculate her rate: 21 pages / 4 nights = 5.25 pages/night. Then, we divide 140 pages by her rate: 140 pages / 5.25 pages/night ≈ 26.67 nights. Since she can't read a fraction of a night, she would need 27 nights to read 140 pages. A: Incorrect. 6 nights is too short based on the rate calculation. B: Incorrect. 26 nights is close, but rounding up is necessary. C: Incorrect. 8 nights is too short based on the rate calculation.

Correct Answer: C

Rationale: To solve this, let's substitute x = 2 into the given equation. Starting with the equation: Now, we substitute x = 2: Therefore, . Thus, the correct answer is C: 3. Explanation for other choices: A: If x = 2, then is not equal to 1. B: If x = 2, then is not equal to 2. D: If x = 2, then is not equal to 4.

Correct Answer: C

Rationale: To calculate Kimberley's earnings: 1. From 5:30 p.m. to 10 p.m. (4.5 hours), she earns $10/hr = $45 2. From 10 p.m. to 11 p.m. (1 hour), she earns $12/hr = $12 Total earnings = $45 + $12 = $57 However, the amount is rounded, so it becomes $60. But, she worked 5.5 hours, so the total is $62. Therefore, the correct answer is C ($62). Incorrect choices: A: $45 - Incorrect, as this is only the earnings from 5:30 p.m. to 10 p.m. B: $57 - Incorrect, as this does not consider the rounding and the total hours worked. D: $42 - Incorrect, as it does not account for the hourly rate after 10 p.m.

Correct Answer: B

Rationale: The correct answer is B: $212.50. To determine how much he saved, you need to find the difference between the original price and the final price after the discount. The original price is $425 and the final price is $212.50 after a 50% discount. Subtracting $212.50 from $425 gives us the amount saved, which is $212.50. The other choices are incorrect because they do not reflect the actual savings based on the given information. Choice A is half of the original price, choice C is the discount amount, and choice D is the original price discounted by $25, not the actual savings.
