TEAS Practice Math Test

Correct Answer: B

Rationale: To find the average weight of each item, we first subtract Jerry's weight from the elevator's weight limit: 800 - 200 = 600 pounds. Then, we divide this by the number of items (4): 600 / 4 = 150 pounds. This means each item should weigh 150 pounds on average to not exceed the weight limit. Choice B (150 pounds) is correct. Choice A (128 pounds) is too light, which would allow the elevator's weight limit to be exceeded. Choice C (175 pounds) and choice D (180 pounds) are too heavy, which would also exceed the weight limit.

Correct Answer: A

Rationale: To calculate Jonathan's monthly bill for x roaming minutes, we need to add the flat rate of $65 to the charge per minute of $0.12 multiplied by the number of roaming minutes x. Therefore, the correct expression is 65 + 0.12x. Choice A (65 + 0.12x) is correct because it accurately represents the total bill by adding the flat rate and the variable charge for roaming minutes. Choices B (65x + 0.12), C (65.12x), and D (65 + 0.12x) are incorrect because they do not correctly combine the flat rate and the charge per minute for roaming. Choice B incorrectly multiplies the flat rate by the variable x, Choice C combines the flat rate and the charge incorrectly, and Choice D does not account for the flat rate in the correct way.

Correct Answer: C

Rationale: To find the number of students who passed the exam, we first need to determine the total number of students who took the exam. Since half of the nursing students took the exam, the number of students who took the exam is 200/2 = 100. Then, three-fifths of those who took the exam passed, which is 3/5 * 100 = 60 students. Therefore, the correct answer is C (60). Choice A (120) is incorrect because it represents the total number of nursing students, not the number of students who passed the exam. Choice B (100) is incorrect because it represents the total number of students who took the exam, not the number who passed. Choice D (50) is incorrect because it does not consider the percentage of students who passed the exam.

Correct Answer: A

Rationale: To calculate the percentage of Dr. Lee's patients hospitalized, we need to find 5% of the 30% who developed an infection. 5% of 30% is 1.5%. Therefore, the correct answer is A: 1.50%. Choice B (5%) is incorrect because it represents the percentage of patients who developed an infection, not those hospitalized. Choice C (15%) is incorrect as it is the total percentage of patients who developed an infection, not just those hospitalized. Choice D (30%) is incorrect as it represents the initial percentage of patients who developed an infection, not those hospitalized.

Correct Answer: A

Rationale: To find the total months required for Robert to secure 24 clients, we can set up a proportion: 3 clients/8 months = 24 clients/x months. Cross multiplying gives us 3x = 192, so x = 64 months. Therefore, the correct answer is A (64 months). The other choices are incorrect because they do not yield the correct solution when the proportion is applied. B (58 months), C (52 months), and D (66 months) do not align with the correct calculation based on the given information.
