Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: 1328.35. To calculate the total cost, we first add up the costs of airfare, hotel (5 nights), sightseeing, and meals. Next, we calculate the cost of additional hotel nights after the 10% discount. Finally, we sum up all the costs to get the total amount Margery will spend. The other choices are incorrect because they do not follow the correct calculation process or include the discount on additional hotel nights.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Sum of two odd numbers is always even (odd + odd = even). 2. Sum of two even numbers is always even (even + even = even). 3. Sum of an odd number and an even number is always odd (odd + even = odd). Therefore, the sum of two odd numbers, two even numbers, an odd number, and an even number would be Even + Even + Odd + Odd = Even. Summary: Choice A is correct as it follows the rules of adding odd and even numbers. Choices B, C, and D are incorrect as they incorrectly state the outcomes of adding odd and even numbers.

Correct Answer: A

Rationale: The correct answer is A: x + 4 = 5/6y - 2. To break it down step-by-step: 1. "Four more than a number" translates to x + 4. 2. "2 less than 5/6 of another number" translates to 5/6y - 2. 3. Combining the two expressions gives x + 4 = 5/6y - 2, which represents the given relationship accurately. In summary, choice A is correct because it correctly captures the relationship described in the question. Choices B, C, and D are incorrect because they do not accurately represent the relationship between the two numbers given in the question.

Correct Answer: C

Rationale: To find the percentage of the time Cora did not fall, we subtract the number of times she fell (20) from the total times she skated (27). So, 27 - 20 = 7 times she did not fall. Then, we divide the number of times she did not fall (7) by the total times she skated (27), which is 7/27 ≈ 0.26 or 26%. Therefore, the correct answer is C. Choice A, B, and D are incorrect because they do not accurately represent the percentage of the time Cora did not fall based on the given information.

Correct Answer: B

Rationale: To calculate a 30% decrease, you multiply the current dosage (340 mg) by 0.30 to find the decrease amount: 340 mg x 0.30 = 102 mg. Subtract the decrease from the current dosage to get the new dosage: 340 mg - 102 mg = 238 mg (Option B). Option A (70 mg) is incorrect as it represents a 79% decrease. Option C (270 mg) is incorrect as it does not account for the 30% decrease. Option D (340 mg) is incorrect as it does not reflect the required decrease.
