TEAS Test Practice Math

Correct Answer: C

Rationale: The correct answer is C: $36. The question states that each roommate contributes $12. Therefore, to find the total amount, we multiply $12 by the number of roommates (3 roommates x $12 = $36). This calculation gives us the estimated total amount of money the roommates used to purchase the gift. Choice A: $34 is incorrect because it does not account for all three roommates contributing $12 each. Choice B: $35 is incorrect as it also does not consider all three roommates contributing $12 each. Choice D: $37 is incorrect because it exceeds the total amount that can be obtained by multiplying $12 by 3.

Correct Answer: A

Rationale: To find the actual distance in miles, multiply the map distance by the scale factor. 3.2 inches * 45 miles/inch = 144 miles. Choice A is correct because it correctly applies the scale factor. Choices B, C, and D are incorrect because they do not properly calculate the actual distance using the scale provided on the map.

Correct Answer: B

Rationale: To calculate the total amount paid with financing: $1000 (down payment) + ($120/month * 12 months/year * 2 years) = $1000 + $2880 = $3880 To find out how much more he would pay with financing: $3880 - $1000 (if paid in one payment) = $2880 Therefore, the man would pay $2880 more with the financing plan, which aligns with choice B: $1280 more. Choices A, C, and D are incorrect as they do not accurately reflect the additional amount paid compared to paying in one payment.

Correct Answer: C

Rationale: To find the circumference of a circle, we use the formula C = 2πr, where r is the radius. Given that the radius is 3 inches, we substitute r = 3 into the formula: C = 2π(3) = 6π ≈ 18.85 inches. The best estimate among the choices is C: 18 inches, as it is closest to the actual calculated value of 18.85 inches. Choice A (12 inches) and B (16 inches) are too small, while choice D (24 inches) is too large compared to the calculated circumference.

Correct Answer: B

Rationale: To solve the equation, we first distribute the 3 to both terms inside the parentheses: 6y + 150 - 4y = 500. Combining like terms, we get 2y + 150 = 500. Next, we isolate the variable by subtracting 150 from both sides, giving us 2y = 350. Finally, we divide by 2 to solve for y, resulting in y = 175. Choice B is correct because it correctly follows the order of operations and simplifies the equation accurately. Choices A, C, and D are incorrect as they do not yield the correct value of y when substituted back into the original equation.
