Correct Answer: C

Rationale: To find the perimeter of a rectangle, we add up all four sides. Given length = 12 cm, width = 5 cm. Perimeter = 2(length) + 2(width) = 2(12) + 2(5) = 24 + 10 = 34 cm. Therefore, the correct answer is C (34 cm). Choice A (17 cm) is incorrect, as it only considers the length and width separately. Choice B (24 cm) is incorrect, as it only adds the length and width once each. Choice D (40 cm) is incorrect, as it incorrectly doubles both the length and width.

Correct Answer: C

Rationale: To find the total potential savings, we first calculate the 20% discount on the car price: 20% of $26,580 = $5,316. Next, we calculate the total monthly payments saved: 3 payments x $250 = $750. Adding the discount and saved payments gives us a total potential savings of $5,316 + $750 = $6,066. Therefore, choice C is correct. Choice A is incorrect because it does not account for the monthly payments saved. Choice B is incorrect as it only considers the discount on the car price, ignoring the saved payments. Choice D is incorrect as it overestimates the savings by combining the discount and payments saved twice.

Correct Answer: D

Rationale: To solve the equation 8x - 6 = 3x + 24, first, simplify both sides. Subtract 3x from both sides to get 5x - 6 = 24. Then, add 6 to both sides to get 5x = 30. Finally, divide by 5 to find x = 6. This is the correct solution as it satisfies the original equation. Choice A, B, and C are incorrect as they do not result in a true statement when substituted back into the equation.

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 calculate Matt's new wage, we need to add the 3/20 increase to his original wage w. So, the new wage is w + 3/20w = 23/20w = 1.15w, which corresponds to choice D. Choice A is incorrect as it represents a decrease. Choice B is incorrect as it represents a smaller increase. Choice C is incorrect as it represents a larger increase than what Matt received.
