TEAS Math Practice Test

Correct Answer: A

Rationale: The correct answer is A: 75 dollars per gigabyte. The slope of the equation represents the rate of change in cost per unit change in data usage. In this case, for every additional gigabyte of data used (D), the cost of the phone bill (C) increases by $75. This interpretation aligns with the equation C = 50 + 75D, where 75 is the coefficient of D, indicating the cost per gigabyte. Summary of other choices: B: 75 gigabytes per day - This is incorrect as it does not reflect the cost per gigabyte relationship in the equation. C: 50 dollars per day - This is incorrect as it does not account for the cost associated with data usage. D: 50 dollars per gigabyte - This is incorrect because the correct cost per gigabyte is $75, not $50.

Correct Answer: A

Rationale: To find the sum of 3/8 and 5/8, you add the numerators together which gives you 3 + 5 = 8. The denominator remains the same (8). So, the sum is 8/8 which simplifies to 1 whole. Therefore, the correct answer is A: 1. Choice B is incorrect as 1 1/4 is greater than 1. Choice C is incorrect as 01-Feb is not a valid fraction. Choice D is incorrect as 03-Apr is not a valid fraction.

Correct Answer: D

Rationale: To find the fraction the fourth person pays, we need to calculate the sum of fractions paid by the first three people. 1/3 + 1/4 + 1/6 = 4/12 + 3/12 + 2/12 = 9/12. Therefore, the fourth person pays 1 - 9/12 = 3/12 or 1/4 of the bill. Choice D (1/12) is incorrect as it does not account for the fractions paid by the other three people. Choices A (1/4), B (1/6), and C (1/3) are incorrect as they represent the fractions paid by other individuals, not the fourth person.

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A: Multiplication. In the expression 8 + 5 * 3, multiplication should be completed first according to the order of operations (PEMDAS/BODMAS). Multiplication takes precedence over addition, so 5 * 3 should be calculated first, resulting in 15. Then, you can add 8 to 15 to get the final answer of 23. Summary: - Choice B: Addition should be done after multiplication in this expression. - Choice C: Division is not involved in the given expression. - Choice D: Subtraction is not applicable until after multiplication and addition are completed.
