TEAS 7 Math Practice Test

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: To calculate a 20% decrease from 400 mg, we first find 20% of 400, which is 80 mg. Subtracting 80 mg from the current dosage of 400 mg gives us the new dosage after the decrease: 400 mg - 80 mg = 320 mg. Therefore, the correct answer is B (80 mg). Choices A, C, and D are incorrect as they do not accurately reflect a 20% decrease from the original 400 mg dosage.

Correct Answer: A

Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.

Correct Answer: D

Rationale: To find the actual distance, we multiply the distance on the map by the scale factor. 3.2 inches x 45 miles = 144 miles. Therefore, choice D is correct. Choice A is incorrect because it uses the scale factor incorrectly. Choice B and C are incorrect as they do not consider the correct scale factor in the calculation.

Correct Answer: C

Rationale: To solve the equation 3(x + 4) = 18 for x, first distribute the 3: 3x + 12 = 18. Then, isolate x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to find x = 2. Therefore, the correct answer is x = 6. Choice A is incorrect because x = 2, not 6. Choice B is incorrect because x = 4, not 6. Choice D is incorrect because x = 8, not 6.
