HESI A2 Quizlet Math

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: B

Rationale: To find the number of people who can swim, multiply the total number of people surveyed by the percentage that can swim. In this case, 120 x 0.85 = 102. Choice B is correct. Choice A is too low as it doesn't account for the 85%. Choice C is too high. Choice D is also too low.

Correct Answer: A

Rationale: 125% can be written as 125/100, which simplifies to 5/4 by dividing both numerator and denominator by the greatest common divisor (25). This is the correct fraction representation of 125%. Choice B (1/8) is incorrect as it represents 12.5%. Choice C (5/2) is incorrect as it represents 250%. Choice D (25/2) is incorrect as it represents 1250%.

Correct Answer: C

Rationale: To find the percentage of 8 in 40, divide 8 by 40 and multiply by 100. (8/40) * 100 = 20%. Therefore, the correct answer is C (10%). Choice A (20%) is incorrect as it represents the opposite relationship. Choices B (15%) and D (25%) are also incorrect as they do not reflect the accurate calculation based on the given values.
