TEAS 7 Math Practice Test

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: 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

Correct Answer: C

Rationale: To determine the number of male patients not overweight as children, we first find the total number of male patients by calculating 30% of 100, which equals 30. Then, we find the number of overweight men (10% of 30), which is 3. Subtracting 3 from the total number of male patients gives us the number of male patients not overweight as children, which is 27 (30 - 3 = 27). Therefore, the correct answer is C. Option A is too low, B does not account for the overweight men, and D is too high based on the calculations.

Correct Answer: A

Rationale: The correct answer is A: Shifts = (2)(5) + 4. 1. Nurse Cameron worked 5 shifts in week 1. 2. In week 2, she worked twice as many shifts as in week 1, which is 2 * 5 = 10 shifts. 3. In week 3, she added 4 shifts to the number of shifts worked in week 2, which is 10 + 4 = 14 shifts. 4. Therefore, the equation describing the number of shifts Nurse Cameron worked in week 3 is (2)(5) + 4 = 10 + 4 = 14 shifts. Summary of incorrect choices: B: Shifts = (4)(5) + 2 - Incorrect because it does not account for the doubling of shifts in week 2 and the addition of 4 shifts in week 3. C: Shifts = 5 + 2 + 4 - Incorrect as it
