Correct Answer: A

Rationale: To find the sale price after a 20% discount, we first calculate the discount amount: 20% of $30 is $6. Subtracting this discount from the original price gives us the sale price: $30 - $6 = $24, which is choice A. Other choices are incorrect as they do not reflect the correct calculation of the discount. B, C, and D are all higher than the correct answer, indicating incorrect calculations.

Correct Answer: D

Rationale: To solve the expression, we follow the order of operations (PEMDAS). First, we evaluate the parentheses: 3 - 4 = -1. Then, we multiply 7 by -1 to get -7. Next, we subtract -7 from 102 to get 109. Finally, subtract 25 from 109 to get the correct answer of 84 (D). Choices A, B, and C are incorrect because they do not follow the correct order of operations or make calculation errors.

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A: 13% decline. To calculate the overall percentage growth or decline in business, we need to consider the weighted average change. First, calculate the weighted average change for print subscriptions: (40% decrease x 70% weight) = 28% decrease. Then, calculate the weighted average change for online subscriptions: (60% increase x 25% weight) = 15% increase. Finally, subtract the increase from the decrease to get the overall change: 15% - 28% = -13%. Therefore, there is a 13% decline in business. Summary: A: 13% decline - Correct B: 15% decline - Incorrect, as it doesn't account for the weighted average. C: 28% growth - Incorrect, as it doesn't consider the decrease in print subscriptions. D: 8% growth - Incorrect, as it doesn't consider the weighted average change.

Correct Answer: D

Rationale: To convert a decimal to a fraction, we count the number of decimal places and put the digits after the decimal over the appropriate power of 10. For 3.28, there are two decimal places, so we write it as 328/100. Simplifying gives us 41/25, which matches choice D. Choices A, B, and C are incorrect as they do not represent the value of 3.28 when converted to a fraction. Option A is equivalent to 3.28 written as 3.28/1, which is not correct. Options B and C do not represent 3.28 accurately either.
