TEAS Math Questions

Correct Answer: A

Rationale: To find the percentage of the total staff that is certified and available to work in the neonatal unit during the holiday, we need to multiply the percentages of staff available and certified. First, calculate the percentage of staff available: 100% - 35% (staff on vacation) = 65% available. Then, calculate the percentage of staff certified among those available: 65% (staff available) * 20% (certified) = 13%. Therefore, the correct answer is B: 0.13, representing 13% of the total staff that is certified and available to work in the neonatal unit during the holiday. The other choices are incorrect because they do not accurately represent the calculated percentage.

Correct Answer: C

Rationale: To calculate the total time, first find the time for the first segment: 305 miles / 65 mph = 4.69 hours. Then, add the 15-minute stop: 15 minutes / 60 = 0.25 hours. Next, find the time for the second segment: 162 miles / 80 mph = 2.025 hours. Add up all the times: 4.69 + 0.25 + 2.025 = 6.965 hours. Since this is closest to 6.69 hours (choice C), that is the correct answer. Choices A, B, and D are incorrect because they do not accurately represent the total time elapsed since the trip began.

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: B

Rationale: To solve the expression, follow the order of operations (PEMDAS). First, multiply 2 by 8 to get 16. Then, add -3 and 16 to get 13. Finally, add 3 to 13 to get 16. Therefore, the correct answer is 13. Choice A (11) is incorrect because it does not account for the correct order of operations. Choice C (28) is incorrect as it only considers the addition of -3 and 3. Choice D (80) is incorrect as it wrongly multiplies 2 by 8 before adding -3.

Correct Answer: C

Rationale: To calculate the correct dosage for the child, we divide the required dosage (240 mg) by the concentration of acetaminophen in the drops (20 mg/mL). This gives us 12 mL as the correct amount. Therefore, the child should receive 2.4 mL (12 mL divided by 5) of concentrated infant drops. Option C is correct because it accurately represents the calculated dosage. Options A, B, and D are incorrect as they do not reflect the correct calculation based on the concentration and required dosage.
