TEAS Practice Math Test

Correct Answer: A

Rationale: The correct answer is A because it shows a direct proportion between the initial deposit and the monthly deposits. The relationship is proportional as the amount deposited per month remains constant ($125). This indicates a consistent ratio between the initial deposit and subsequent deposits. B is incorrect as it involves a fixed hourly rate and a bonus, not a proportional relationship. C is incorrect as it involves fixed monthly cost and variable cost per minute, not a proportional relationship. D is incorrect as it states a constant rate of speed, not a proportional relationship based on changing variables.

Correct Answer: B

Rationale: To calculate the new dosage after a 30% decrease, we multiply the current dosage (340 mg) by (100% - 30%) = 70%. 340 mg * 70% = 340 mg * 0.70 = 238 mg. Therefore, the correct answer is B. Choice A (70 mg): This is incorrect because it represents a 30% decrease from 100 mg, not the initial dosage of 340 mg. Choice C (270 mg): This is incorrect because it does not account for the 30% decrease from the initial dosage of 340 mg. Choice D (340 mg): This is incorrect because the question asks for the dosage after a 30% decrease, not the current dosage.

Correct Answer: C

Rationale: To calculate what Erma will spend, we first find the cost of the cheaper sweater after the discount, which is $44 - (25% of $44) = $44 - $11 = $33. Then, we add the cost of the more expensive sweater, which remains at $50. Therefore, Erma will spend $33 + $50 = $83. The correct answer is C. Option A is incorrect because it does not consider the discount on the cheaper sweater. Option B is incorrect as it underestimates the total cost by not factoring in the discount. Option D is incorrect as it overestimates the total cost by not considering the discount on the cheaper sweater.
