Correct Answer: D

Rationale: To divide 40.3 by 4.8, we perform the division operation as follows: 40.3 ÷ 4.8 = 8.39583... Rounded to one decimal place, the result is 8.4, which is the correct answer (Choice D). Choice A (0.084) is incorrect as it is the result of dividing 40.3 by 480. Choice B (84) is incorrect as it is the result of multiplying 40.3 by 4.8. Choice C (0.84) is incorrect as it is close to the correct answer but not the precise result of the division.

Correct Answer: A

Rationale: To find the total cost of the comics, multiply $2.65 by 3, which equals $7.95. To determine the change, subtract the total cost from the amount paid: $20 - $7.95 = $12.05. Therefore, Robert received $12.05 in change. Option B is incorrect because it miscalculates the change. Option C is incorrect as it only accounts for one comic's cost. Option D is incorrect as it does not consider the total cost of all three comics.

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.
