TEAS 7 Math Practice Test

Correct Answer: D

Rationale: To calculate the increased dosage, we first find 30% of the current dosage: 270 mg x 0.30 = 81 mg. Then, we add this to the current dosage: 270 mg + 81 mg = 351 mg. Therefore, the correct answer is D. Choice A is incorrect as it is less than the current dosage. Choice B is incorrect as it does not account for the increase. Choice C is incorrect as it does not include the correct percentage increase.

Correct Answer: C

Rationale: To find the fraction of the class that wanted to work with the elderly, we add the percentage of students who wanted to work with the elderly, which is 60%. This can be represented as 60/100, which simplifies to 3/5. Choice A (1/4) is incorrect because it represents the fraction of students who wanted to work with infants, which is 25%. Choice B (1/10) is incorrect as it represents the fraction of students who wanted to assist general practitioners, which is 10%. Choice D (1/20) is incorrect as it does not correspond to any of the given percentages in the question.

Correct Answer: C

Rationale: To determine the correct dosage, multiply the patient's weight (60 kg) by the prescribed dosage (5 mg/kg): 60 kg x 5 mg/kg = 300 mg. Choice C is correct. Choices A, B, and D are incorrect as they do not result from the correct calculation. Choice A (100 mg) is too low, Choice B (150 mg) is also too low, and Choice D (400 mg) is too high based on the calculation.

Correct Answer: C

Rationale: To calculate the total amount Margery expects to spend on her vacation, we need to add up all her expenses. The airfare is $572. The hotel costs $89 per night for 5 nights, but she will receive a 10% discount after the first night, so the total hotel cost is (1 night + 4 nights * 0.9) * $89 = $400.10. She has allotted $150 for sightseeing and $250 for meals. Adding all these expenses together: $572 (airfare) + $400.10 (hotel) + $150 (sightseeing) + $250 (meals) = $1,372.10. Therefore, the total amount Margery expects to spend on her vacation is $1,372.10, which is closest to option C: $1,381.40. Options A, B, and D are incorrect because they do not accurately calculate the total expenses based on the
