TEAS Math Questions

Correct Answer: A

Rationale: To calculate the final price after a 20% discount, you first find the discount amount by multiplying the original price ($80) by the discount percentage (20% = 0.20), which equals $16. Then, subtract the discount amount from the original price to get the final price: $80 - $16 = $64. Therefore, the correct answer is A. Choice B ($60) is incorrect because it does not account for the correct discount amount. Choice C ($70) is incorrect as it does not reflect the correct calculation after applying the discount. Choice D ($66) is incorrect as it does not consider the accurate discount percentage applied to the original price.

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: C

Rationale: To determine which group is the smallest, we need to compare the fractions representing the proportion of patients in each group. Group Alpha has 1/2, Group Beta has 1/3, and Group Gamma has 1/6 of the total patients. To find the smallest group, we look for the smallest fraction. Among the choices, 1/6 in Group Gamma is the smallest fraction, hence Group Gamma is the smallest group. Incorrect choices: A: Group Alpha - 1/2 is larger than 1/3 and 1/6, making it larger than Group Beta and Group Gamma. B: Group Beta - 1/3 is larger than 1/6 but smaller than 1/2, making it larger than Group Gamma. D: Group Delta - This is not a valid choice in the question, so it is incorrect.

Correct Answer: A

Rationale: The correct answer is A. To determine which group has the largest number of patients, we need to find the group with the largest fraction. Comparing 1/2, 1/3, and 1/6, 1/2 is the largest fraction. Therefore, the group represented by 1/2 has the largest number of patients. Summary of other choices: B: Beta - Represents 1/3, which is smaller than 1/2. C: Gamma - Represents 1/6, which is smaller than both 1/2 and 1/3. D: Delta - No fraction is provided, so we cannot compare it to the other groups.

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.
