TEAS Math Questions

Correct Answer: B

Rationale: The correct answer is B: $1,280 more. In the financing plan, the total cost is $1,000 (down payment) + ($120 x 24 months) = $1,000 + $2,880 = $3,880. The difference between paying in cash and choosing the financing plan is $3,880 - $2,600 = $1,280. Therefore, the man would pay $1,280 more with the financing plan. A: $1,480 more - Incorrect because it miscalculates the total cost of the financing plan. C: $1,600 more - Incorrect as it overestimates the additional payment compared to the cash option. D: $2,480 more - Incorrect as it includes the total cost of the furniture itself, not just the additional cost of the financing plan.

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.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Start with the original price: $100 2. Calculate the discount amount: 15% of $100 = $15 3. Subtract the discount from the original price: $100 - $15 = $85 4. Therefore, the price after the 15% discount is $85. Summary of incorrect choices: A. $90: Incorrect, as this is the original price minus a 10% discount. C. $80: Incorrect, as this is the original price minus a 20% discount. D. $75: Incorrect, as this is not the correct calculation for a 15% discount.

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.

Correct Answer: B

Rationale: To calculate the probability of consecutively pulling 2 orange blocks without replacement, we first find the probability of pulling 1 orange block, then the probability of pulling another orange block. 1. Probability of first orange block = 3/12 = 1/4 2. After removing 1 orange block, there are 2 orange blocks left out of 11 total blocks. 3. Probability of second orange block = 2/11 4. Multiply the probabilities: (1/4) * (2/11) = 2/44 = 1/22 5. Simplify the fraction: 1/22 = 2/44 = 3/66 = 3/55 Therefore, the correct answer is B (3/55) as it represents the probability of consecutively pulling two more orange blocks without replacement. Other choices are incorrect as they do not follow the correct calculation steps.
