ATI TEAS Math Practice Test

Correct Answer: A

Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.

Correct Answer: A

Rationale: The correct answer is A: y = 15 + 28x. This equation represents the total amount of money Andy will have saved. Initially, he has $15 saved (y = 15 when x = 0). Then, he saves $28 per month, which is represented by 28x. Therefore, the total amount saved is the initial $15 plus the monthly savings of $28 times the number of months x. Summary: - Choice A is correct because it includes the initial savings of $15 and the monthly savings of $28x. - Choice B is incorrect because it incorrectly adds $15 to the monthly savings. - Choice C is incorrect because it only represents the monthly savings without considering the initial amount saved. - Choice D is incorrect because it adds the monthly savings before the initial amount saved.

Correct Answer: B

Rationale: To calculate the percentage more female staff at Hospital Y than X, we first find the difference in the percentage of female staff between the two hospitals. Let's say Hospital X has 40% female staff and Hospital Y has 50%. The difference is 50% - 40% = 10%. This means that Hospital Y has 10% more female staff than Hospital X. Therefore, the correct answer is B (10%). Option A (5%) is incorrect because the actual percentage more is 10%. Option C (15%) and D (20%) are incorrect as they overestimate the difference in female staff percentages between the two hospitals.

Correct Answer: B

Rationale: To simplify the expression 13 - 3/22 - 11, we first calculate 3/22 which is 0.136. Then, we subtract 0.136 from 13, resulting in 12.864. Lastly, we subtract 11 from 12.864, giving us 1.864. Therefore, the correct answer is B: 7/22. Choices A, C, and D are incorrect as they do not match the simplified expression value of 1.864.

Correct Answer: D

Rationale: To determine the number of questions Joshua must answer correctly, we can use the inequality 4x > 92, where x represents the number of questions answered correctly. This is because each correct answer earns 4 points, and Joshua needs more than 92 points to qualify for the scholarship. To solve for x, we divide both sides by 4, giving us x > 23. So, Joshua must answer more than 23 questions correctly to qualify. Choices A, B, and C are incorrect because: A (4x < 30): This inequality suggests Joshua needs to answer less than 30 questions in total, which is not relevant to the scholarship qualification. B (4x < 92): This inequality implies Joshua needs less than 92 points, which contradicts the requirement of earning more than 92 points. C (4x > 30): This inequality indicates Joshua needs to answer more than 30 questions in total, but it does not consider the points required for
