Practice Math TEAS TEST

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: B

Rationale: The independent variable is the one that is manipulated or changed by the researcher in an experiment. In this scenario, the number of credit hours a student takes is the variable that is being controlled or changed to observe its effect on other variables such as tuition, access fees, and student loans. The amount of credit hours is not dependent on any other variable in this context, making it the independent variable. In contrast, the amount of tuition, access fees, and student loans are dependent on the number of credit hours taken by the student, making them dependent variables. Therefore, the correct answer is B: Number of credit hours. Choices A, C, and D are incorrect as they are all dependent variables that are influenced by the number of credit hours taken by the student.

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: A

Rationale: To find the sum of three times a number and eight times a different number, we need to add 3 times the first number (3x) to 8 times the second number (8y). Therefore, the correct expression is 3x + 8y (Choice A). This choice correctly represents the operation of adding the terms. Choices B, C, and D either incorrectly combine the coefficients of x and y or use subtraction instead of addition, making them incorrect for this question.

Correct Answer: D

Rationale: Step 1: Let x be the original price of the recliner. Step 2: Sale price = x - 0.3x = 0.7x Step 3: Price after coupon = 0.7x - 0.25(0.7x) = 0.525x Step 4: Set up equation: 0.525x = 237 Step 5: Solve for x: x = 237 / 0.525 ≈ $451 Step 6: The original price is closest to $451, making option C incorrect. Step 7: Check why other choices are incorrect: - Option A: $316 is too low for the original price. - Option B: $431 is the calculated sale price, not the original price. - Option D: $527 is the original price based on the calculation.
