TEAS Test Practice Math

Correct Answer: B

Rationale: To find the least number of computers to be shipped and sold for the amount received to be equal to shipping cost, we set the selling amount equal to the shipping cost: 400x = 3000 + 100x Solving for x, we get x = 15. Therefore, the correct answer is B. Choice A (10) is too low as it results in less revenue than the shipping cost. Choices C (20) and D (25) are higher than the minimum required number of 15 computers, resulting in more revenue than needed.

Correct Answer: B

Rationale: To solve the equation, we first distribute the 3 to both terms inside the parentheses: 6y + 150 - 4y = 500. Combining like terms, we get 2y + 150 = 500. Next, we isolate the variable by subtracting 150 from both sides, giving us 2y = 350. Finally, we divide by 2 to solve for y, resulting in y = 175. Choice B is correct because it correctly follows the order of operations and simplifies the equation accurately. Choices A, C, and D are incorrect as they do not yield the correct value of y when substituted back into the original equation.

Correct Answer: C

Rationale: To find the total number of clients secured in a given time, we divide the total clients by the clients secured in one period. 24 clients ÷ 3 clients/8 months = 8 periods. To find the total time, we multiply the periods by the time for one period. 8 periods × 8 months = 64 months. Therefore, Robert has secured 24 new clients after 64 months. The other choices are incorrect because they do not align with the correct calculation.

Correct Answer: C

Rationale: To find the milliliters of blood used for further tests, we first calculate 16.66% of 500 ml: 500 ml x 0.1666 = 83.33 ml. Therefore, the correct answer is C. Choice A is incorrect as it does not account for rounding to the nearest hundredth. Choice B is incorrect as it does not include the exact decimal value. Choice D is incorrect as it rounds up instead of rounding to the nearest hundredth.

Correct Answer: C

Rationale: To find the total percent deducted, you add the percentages taken for taxes and insurance. 35% + 4% = 39%. Therefore, the correct answer is C (39%). Choice A (20%) is too low, as it only considers the tax deduction. Choice B (31%) and Choice D (42%) are incorrect because they don't account for both deductions.
