TEAS Math Questions

Correct Answer: C

Rationale: To determine the number of male patients NOT overweight as children, calculate the total number of male patients: 30% of 100 patients = 30 male patients. Then, find the number of overweight male patients: 10% of 30 male patients = 3 overweight males. Subtract the overweight males from the total male patients to get the number of male patients NOT overweight: 30 - 3 = 27. Therefore, the correct answer is C (27). Choice A (3) is incorrect because it represents the number of overweight male patients, not the number of male patients NOT overweight. Choice B (10) is incorrect as it does not consider the calculation of overweight male patients and total male patients. Choice D (30) is incorrect as it represents the total number of male patients, not the number of male patients NOT overweight.

Correct Answer: A

Rationale: To find the percentage of staff certified and available during the holiday, we first calculate the remaining staff after 35% are on vacation (100% - 35% = 65%). Then, 20% of the remaining 65% are certified (20% of 65% = 0.20 * 65% = 13%). Therefore, the percentage of staff certified and available is 13% (0.13), which corresponds to choice B. However, the question asks for the percentage, not the decimal representation. To convert 0.13 to a percentage, we multiply by 100, resulting in 13%. Therefore, the correct answer is A (0.13 expressed as a percentage is 13%). Choices C and D are incorrect as they do not match the calculated percentage.

Choice B (10) is incorrect as it does not consider the calculation of overweight male patients and total male patients. Choice D (30) is incorrect as it represents the total number of male patients, not the number of male patients NOT overweight.

Correct Answer: B

Rationale: Veronica's total cost is the sum of the base price, surround sound system, and maintenance package: $40,210 + $3,015 + $5,218 = $48,443. This is the correct answer (B) as it calculates the total price accurately. Option A is incorrect as it only includes the base price. Option C is incorrect as it does not include the additional costs. Option D is incorrect as it only includes the base price without the additional expenses.

Correct Answer: A

Rationale: To calculate how many liters are left after using 25%, we first find 25% of 10 liters: 10 * 0.25 = 2.5 liters used. Subtracting this from the initial amount gives us the remaining water: 10 - 2.5 = 7.5 liters left. Therefore, choice A (7.5 liters) is correct. Choice B (8 liters) is incorrect because it doesn't account for the water that was used. Choice C (6.5 liters) and choice D (8.5 liters) are also incorrect as they do not reflect the correct calculation based on the given information.
