TEAS 7 Math Practice Test

Correct Answer: C

Rationale: To determine the correct dosage, multiply the patient's weight (60 kg) by the prescribed dosage (5 mg/kg): 60 kg x 5 mg/kg = 300 mg. Choice C is correct. Choices A, B, and D are incorrect as they do not result from the correct calculation. Choice A (100 mg) is too low, Choice B (150 mg) is also too low, and Choice D (400 mg) is too high based on the calculation.

Correct Answer: B

Rationale: The correct answer is B (25). To find the range, subtract the smallest value from the largest value in a set of data. Given the options, 32 (largest) minus 7 (smallest) equals 25. Therefore, the range in the number of flights the flight attendant made is 25. Option A (20) is incorrect as it is smaller than the actual range. Option C (29) and D (32) are incorrect because they are larger than the actual range, making them invalid choices.

Correct Answer: B

Rationale: Correct Answer: B Rationale: In January, Dr. Lewis worked 20 shifts. In February, she worked 3 times as many shifts as in January (3 * 20 = 60 shifts). In March, she worked half the number of shifts she worked in February (1/2 * 60 = 30 shifts). Therefore, the equation should be shifts = (20)(3)(1/2) = 30, which accurately represents the number of shifts Dr. Lewis worked in March. Summary of other choices: A: Incorrect because it adds shifts for each month without considering the relationships between them. C: Incorrect because it multiplies January and February shifts but does not account for March being half of February. D: Incorrect because it incorrectly multiplies 3 and 1/2 without considering the total number of shifts in February.

Correct Answer: D

Rationale: To calculate the sale price Gordon paid, we first find the discount amount by multiplying the original price by the discount percentage: $472 * 0.30 = $141.60. The sale price is the original price minus the discount amount: $472 - $141.60 = $330.40. Therefore, the correct answer is D. Choice A is incorrect because it only represents the discount amount, not the final sale price. Choice B is incorrect as it does not account for the discount. Choice C is incorrect as it is higher than the correct sale price.

Correct Answer: A

Rationale: To find the combinations Tom can purchase, you need to determine the total cost of ink cartridges and paper. Let c be the number of cartridges and p be the number of reams. The total cost is 30c + 5p. Since Tom has $100, the inequality is 30c + 5p ≤ 100. This is because the total cost should not exceed $100. Therefore, choice A is correct. Choice B is incorrect because it implies Tom can only spend exactly $100, which restricts his options. Choice C is incorrect as it states the total cost must be more than $100, which goes against the budget constraint. Choice D is incorrect as it allows for the total cost to be less than $100, which is not a valid option given Tom's budget.
