TEAS 7 Math Practice Test

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.

Correct Answer: A

Rationale: The correct answer is A (3/5). To calculate the total fraction spent, we add 1/2 (for office administrator) and 1/10 (for office supplies): 1/2 + 1/10 = 5/10 + 1/10 = 6/10 = 3/5. The other choices are incorrect as they do not accurately represent the sum of the fractions allocated for the office administrator and office supplies. Option B (2/12), C (2/20), and D (1/20) do not reflect the correct calculation based on the information provided in the question.

Correct Answer: A

Rationale: To find the combinations Tom can purchase, you need to determine the total cost of ink cartridges and paper. Let c be the number of cartridges and p be the number of reams. The total cost is 30c + 5p. Since Tom has $100, the inequality is 30c + 5p ≤ 100. This is because the total cost should not exceed $100. Therefore, choice A is correct. Choice B is incorrect because it implies Tom can only spend exactly $100, which restricts his options. Choice C is incorrect as it states the total cost must be more than $100, which goes against the budget constraint. Choice D is incorrect as it allows for the total cost to be less than $100, which is not a valid option given Tom's budget.

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

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.
