TEAS Practice Math Test

Correct Answer: D

Rationale: The correct answer is D: $144.65. To find the total cost of Susan's outfit, you need to add up the costs of the dress, shoes, and accessories. $69.99 (dress) + $39.99 (shoes) + $34.67 (accessories) = $144.65. This is the total cost of Susan's outfit. Explanation for incorrect choices: A: $69.99 - This is only the cost of the dress and does not include the shoes and accessories. B: $75.31 - This amount is not the total cost as it only includes the dress and shoes, excluding the accessories. C: $109.98 - This sum is the total of the dress and shoes but does not include the accessories. Therefore, the correct answer is D as it includes the combined cost of all items purchased.

Correct Answer: B

Rationale: The median is the middle value when numbers are arranged in ascending order. In this case, when the scores 81, 92, 87, 89, and 94 are arranged in ascending order, the middle value is 89. Therefore, the correct answer is B. Choice A (87) is incorrect as it is not the middle value when arranged in ascending order. Choices C (92) and D (94) are also incorrect as they are not the middle values when the numbers are arranged in ascending order.

Correct Answer: A

Rationale: To determine the correct order, we convert all values to decimals or percentages. First, convert -3/4 to -0.75, then 3% to 0.03. Now, the order becomes -2, -0.75, -0.45, 0.03, 0.36. The correct order is A: -2, -3/4, -0.45, 3%, 0.36. This is correct because -2 is the least, followed by -0.75, then -0.45, 0.03, and finally 0.36. Other choices are incorrect because they do not follow the correct numerical order.

Correct Answer: B

Rationale: To calculate the new dosage after a 30% decrease, we multiply the current dosage (340 mg) by (100% - 30%) = 70%. 340 mg * 70% = 340 mg * 0.70 = 238 mg. Therefore, the correct answer is B. Choice A (70 mg): This is incorrect because it represents a 30% decrease from 100 mg, not the initial dosage of 340 mg. Choice C (270 mg): This is incorrect because it does not account for the 30% decrease from the initial dosage of 340 mg. Choice D (340 mg): This is incorrect because the question asks for the dosage after a 30% decrease, not the current dosage.
