Practice Math TEAS TEST

Correct Answer: B

Rationale: To calculate the percentage increase, subtract the initial value from the final value, then divide by the initial value and multiply by 100. Percentage Increase = [(1072-841)/841] x 100 ≈ 27% Therefore, choice B (27%) is the correct answer as it represents the approximate percentage increase in client volume. Choice A (22%) is incorrect because it does not accurately reflect the calculated percentage increase. Choice C (127%) is incorrect as it is way too high and does not align with the actual increase. Choice D (78%) is incorrect as it is also significantly off from the calculated percentage increase.

Correct Answer: B

Rationale: To find 31% of 426, you multiply 426 by 0.31. So, 426 * 0.31 = 132.06. Therefore, the correct answer is B: 132.06. Option A (425.69) is close but incorrect. Options C (13.7) and D (0.07) are significantly lower than the actual result, indicating they are incorrect.

Correct Answer: A

Rationale: The correct answer is A: Eritrea. To determine the largest increase in healthcare spending per capita from 2013 to 2015, we need to calculate the difference between the spending in 2015 and 2013 for each country. By comparing the dollar amount increase for each country, it is evident that Eritrea experienced the largest increase. This is because the dollar amount increase for Eritrea is greater than that of the other countries listed. Sudan, Tanzania, and Kenya had smaller increases in dollars spent per capita during the same period. Therefore, A is the correct answer.

Correct Answer: B

Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.
