Correct Answer: D

Rationale: To find the total bonus amount, we need to work backwards. Since Chan has $600 remaining after paying taxes, donating, and paying off debt, this $600 represents 15% of his original bonus (100% - 30% - 30% - 25% = 15%). Therefore, $600 is equivalent to 15% of the bonus. To find the total bonus amount, we divide $600 by 15% (or 0.15), which equals $4,000. Thus, the correct answer is D: $4,000. Choice A ($3,000) is incorrect because it does not account for the remaining $600. Choice B ($3,200) and choice C ($3,600) are also incorrect as they do not reflect the correct percentage left after all deductions, which is 15%.

Correct Answer: A

Rationale: The correct answer is A (35). To find the number of students who chose blue, multiply the total number of students by the percentage that chose blue: 100 x 0.35 = 35. This calculation gives us the number of students who said blue is their favorite color. The other choices are incorrect because they do not correctly calculate the number of students who chose blue based on the given percentage. Choice B (25), C (20), and D (10) do not accurately represent 35% of the total number of students. Therefore, choice A is the correct answer based on the calculation method provided.

Correct Answer: D

Rationale: To solve for x, we add 7 to both sides of the equation: 2x - 7 + 7 = 3 + 7. This simplifies to 2x = 10. Then, we divide both sides by 2 to solve for x: 2x/2 = 10/2, which gives x = 5. Therefore, the correct answer is D. Choice A is incorrect because 4 does not satisfy the equation. Choice B is incorrect as x = 3 does not make the equation true. Choice C is incorrect as x = -2 does not satisfy the equation either.

Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A because it shows a direct proportion between the initial deposit and the monthly deposits. The relationship is proportional as the amount deposited per month remains constant ($125). This indicates a consistent ratio between the initial deposit and subsequent deposits. B is incorrect as it involves a fixed hourly rate and a bonus, not a proportional relationship. C is incorrect as it involves fixed monthly cost and variable cost per minute, not a proportional relationship. D is incorrect as it states a constant rate of speed, not a proportional relationship based on changing variables.
