TEAS Math Questions

Correct Answer: B

Rationale: To solve the equation x + x * x - x / x, we follow the order of operations (PEMDAS/BODMAS). First, we calculate x * x = x^2, then x / x = 1. So the equation becomes x + x^2 - 1. Simplifying further, we get x^2 + x - 1. This is a quadratic equation. To find the value of x that satisfies this equation, we can factor it or use the quadratic formula. The correct answer is B: 3, as x = 3 satisfies the equation x^2 + x - 1 = 3^2 + 3 - 1 = 9 + 3 - 1 = 11, which matches the left side of the equation. Summary: A: 5 - Incorrect. The value of x that satisfies the equation is not 5. C: 2 - Incorrect. The value of x that satisfies the equation is

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: A

Rationale: The correct answer is A: 1,050 people. To calculate the population next year, we need to add the 5% increase to the current population. 5% of 1,000 is 50, so the population will increase by 50 people. Therefore, the population next year will be 1,000 + 50 = 1,050 people. Choice B (1,200 people) is incorrect because it assumes a 20% increase instead of 5%. Choice C (1,100 people) is incorrect because it does not consider the 5% increase. Choice D (1,300 people) is incorrect as it implies a 30% increase, which is not accurate based on the given 5% annual increase.

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.

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.
