TEAS Practice Math Test

Correct Answer: C

Rationale: To calculate what Erma will spend, we first find the cost of the cheaper sweater after the discount, which is $44 - (25% of $44) = $44 - $11 = $33. Then, we add the cost of the more expensive sweater, which remains at $50. Therefore, Erma will spend $33 + $50 = $83. The correct answer is C. Option A is incorrect because it does not consider the discount on the cheaper sweater. Option B is incorrect as it underestimates the total cost by not factoring in the discount. Option D is incorrect as it overestimates the total cost by not considering the discount on the cheaper sweater.

Correct Answer: A

Rationale: To determine the correct order, we convert all values to decimals or percentages. First, convert -3/4 to -0.75, then 3% to 0.03. Now, the order becomes -2, -0.75, -0.45, 0.03, 0.36. The correct order is A: -2, -3/4, -0.45, 3%, 0.36. This is correct because -2 is the least, followed by -0.75, then -0.45, 0.03, and finally 0.36. Other choices are incorrect because they do not follow the correct numerical order.

Correct Answer: A

Rationale: To find the total months required for Robert to secure 24 clients, we can set up a proportion: 3 clients/8 months = 24 clients/x months. Cross multiplying gives us 3x = 192, so x = 64 months. Therefore, the correct answer is A (64 months). The other choices are incorrect because they do not yield the correct solution when the proportion is applied. B (58 months), C (52 months), and D (66 months) do not align with the correct calculation based on the given information.

Correct Answer: C

Rationale: The mean time for the women who ran the 200m event at the 2008 Olympic Games can be calculated by summing all the times and dividing by the total number of times. Sum of times = 22.33 + 22.50 + 22.50 + 22.61 + 22.71 + 22.72 + 22.83 + 23.22 = 182.42 Total number of times = 8 Mean time = 182.42 / 8 = 22.8025 ≈ 22.68 sec (Choice C) Therefore, the correct answer is C (22.68 sec) as it is the closest to the calculated mean time. Incorrect choices: A: 22.50 sec - This is not the mean of the given times. B: 22.66 sec - Not the mean. D: 22.77 sec - Not the mean.
