TEAS Practice Math Test

Correct Answer: D

Rationale: The correct answer is D: $144.65. To find the total cost of Susan's outfit, you need to add up the costs of the dress, shoes, and accessories. $69.99 (dress) + $39.99 (shoes) + $34.67 (accessories) = $144.65. This is the total cost of Susan's outfit. Explanation for incorrect choices: A: $69.99 - This is only the cost of the dress and does not include the shoes and accessories. B: $75.31 - This amount is not the total cost as it only includes the dress and shoes, excluding the accessories. C: $109.98 - This sum is the total of the dress and shoes but does not include the accessories. Therefore, the correct answer is D as it includes the combined cost of all items purchased.

Correct Answer: D

Rationale: To find the total bonus amount, we need to work backwards. Since Chan has $600 remaining after paying taxes, donating, and paying off debt, this $600 represents 15% of his original bonus (100% - 30% - 30% - 25% = 15%). Therefore, $600 is equivalent to 15% of the bonus. To find the total bonus amount, we divide $600 by 15% (or 0.15), which equals $4,000. Thus, the correct answer is D: $4,000. Choice A ($3,000) is incorrect because it does not account for the remaining $600. Choice B ($3,200) and choice C ($3,600) are also incorrect as they do not reflect the correct percentage left after all deductions, which is 15%.

Correct Answer: D

Rationale: To solve the equation 3(x - 1) = 2(3x - 9), first distribute the terms: 3x - 3 = 6x - 18. Then, isolate x by moving the variables to one side: 3x - 6x = -18 + 3. Simplify to get -3x = -15, and divide by -3 to find x = 5. Choice D is correct as it correctly solves the equation step by step. Choices A, B, and C are incorrect because they do not yield the correct solution when the equation is solved.

Correct Answer: A

Rationale: To calculate the percentage of Dr. Lee's patients hospitalized, we need to find 5% of the 30% who developed an infection. 5% of 30% is 1.5%. Therefore, the correct answer is A: 1.50%. Choice B (5%) is incorrect because it represents the percentage of patients who developed an infection, not those hospitalized. Choice C (15%) is incorrect as it is the total percentage of patients who developed an infection, not just those hospitalized. Choice D (30%) is incorrect as it represents the initial percentage of patients who developed an infection, not those hospitalized.
