TEAS Math Questions

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: 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: A

Rationale: Step 1: Given that y is three times x, the equation should reflect this relationship. Step 2: The equation y = 3x correctly models this relationship, where y is equal to three times x. Step 3: Option A (y = 3x) is the correct choice as it directly represents y as three times x. Summary: Choices B, C, and D do not correctly model the relationship between x and y as specified. Choice B (x = 3y) is the inverse relationship, Choice C (y = x + 3) adds 3 to x instead of representing y as three times x, and Choice D (y = x / 3) represents y as x divided by 3, not three times x.

Correct Answer: A

Rationale: To find the number of hours spent sleeping, we need to calculate 1/4 of a day. Since a day has 24 hours, 1/4 of 24 is 24/4 = 6 hours. Therefore, the correct answer is A: 6 hours. Choice B (8 hours) is incorrect as it is not 1/4 of a day. Choices C (4 hours) and D (5 hours) are also incorrect as they do not represent 1/4 of a day.

Correct Answer: C

Rationale: The correct order is Gamma, Alpha, Beta. Step 1: Find the least common multiple (LCM) of the fractions: LCM of 2, 3, and 6 is 6. Step 2: Calculate the number of patients in each group for a total of 6 patients. Group Alpha: 6 * (1/2) = 3 patients. Group Beta: 6 * (1/3) = 2 patients. Group Gamma: 6 * (1/6) = 1 patient. Therefore, the correct order is Gamma (1 patient), Alpha (3 patients), Beta (2 patients). Choice C is correct as it reflects this order. Choices A, B, and D are incorrect as they do not follow the correct distribution of patients based on the fractions given.
