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: D

Rationale: To determine when Truck B becomes the better buy, we need to find the breakeven point where the total cost of owning and operating both trucks is the same. First, calculate the total cost for each truck by adding the initial cost to the cost of gasoline for the miles driven. For Truck A: $450 + ($4/mile * x miles), and for Truck B: $650 + ($4/mile * x miles). Set these two equations equal to each other and solve for x to find the breakeven point. By solving the equation, we find that Sally must drive 4375 miles for Truck B to be the better buy. The correct answer is D. Summary: A: 500 - Incorrect, too low of a mileage for Truck B to be the better buy. B: 7500 - Incorrect, too high of a mileage for Truck B to be the better buy. C: 1750 - Incorrect, not the correct mileage for Truck B to

Correct Answer: B

Rationale: To convert decimeters to centimeters, we multiply by 10 since 1 decimeter is equal to 10 centimeters. Therefore, for a book with a width of 5 decimeters, the width in centimeters would be 5 * 10 = 50 centimeters. This makes choice B, 25 centimeters, the correct answer. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor from decimeters to centimeters. Choice A is too small, choice C is too large, and choice D is also too small due to incorrect decimal placement.

Correct Answer: B

Rationale: The correct answer is B: Group Z, Group Y, Group X. This is because Group Z has the largest number of doctors, followed by Group Y, then Group X. To determine this, we need to compare the order of each group's size. Group Z > Group Y > Group X in terms of the number of doctors. Choice A (Group X, Group Y, Group Z) is incorrect because it lists the groups in ascending order of doctor numbers, which is opposite to the correct order. Choice C (Group Z, Group X, Group Y) is incorrect as it incorrectly places Group X before Group Y. Choice D (Group Y, Group X, Group Z) is incorrect because it lists the groups in ascending order, which is the opposite of the correct order.

Correct Answer: B

Rationale: The correct answer is B: $86,666.67. To calculate this, divide the total operating expenses ($130,000) by 3, as a general guideline is that one-third of operating expenses typically go towards employee wages and benefits. $130,000 / 3 = $43,333.33. However, this only represents the wages portion, and benefits are typically an additional 50% of wages, making the total amount spent on wages and benefits $43,333.33 + ($43,333.33 * 0.5) = $86,666.67. Choice A: $43,333.33 - This only represents the wages portion and does not include benefits. Choice C: $52,000.00 - This amount does not account for benefits and is not calculated correctly. Choice D: $78,000.00 - This amount is only the wages portion and does not include benefits.
