TEAS 7 Math Practice Test

Correct Answer: B

Rationale: The correct answer is B: 23%. To calculate this, we add up the percentages of the other three options (49% + 18% + 10% = 77%) and subtract it from 100% (100% - 77% = 23%). This gives us the percentage of funds donated to support construction costs. The rationale is that the sum of percentages of all options must add up to 100%. Choice A, C, and D are incorrect as they do not add up to 100% when combined, making B the correct answer.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

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

Correct Answer: A

Rationale: To calculate the percent increase, subtract the initial value from the final value (2219 - 1432 = 787). Then, divide the increase by the initial value and multiply by 100 to get the percentage increase [(787/1432) x 100 ≈ 55%]. Therefore, choice A (55%) is correct. Choice B (36%) is incorrect because it underestimates the actual increase. Choice C (64%) and choice D (42%) are also incorrect as they overestimate the 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.
