TEAS 7 Math Practice Test

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.

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 simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.
