TEAS 7 Math Practice Test

Correct Answer: C

Rationale: To find the cost of one box of crackers, we set up a system of equations. Let x be the cost of one container of yogurt and y be the cost of one box of crackers. From the given information, we have: 4x + 3y = 9.55 2x + 2y = 5.90 Solving the system of equations, we find x = 1.45 and y = 2.25. Therefore, one box of crackers costs $2.25, making choice C the correct answer. Incorrect choices: A: $1.75 - Incorrect because it doesn't match the calculated cost. B: $2.00 - Incorrect, as it does not align with the calculated cost. D: $2.50 - Wrong, as it does not correspond to the calculated value.

Correct Answer: C

Rationale: To determine the number of male patients not overweight as children, we first find the total number of male patients by calculating 30% of 100, which equals 30. Then, we find the number of overweight men (10% of 30), which is 3. Subtracting 3 from the total number of male patients gives us the number of male patients not overweight as children, which is 27 (30 - 3 = 27). Therefore, the correct answer is C. Option A is too low, B does not account for the overweight men, and D is too high based on the calculations.

Correct Answer: C

Rationale: The correct answer is C because it asks for the greatest percentage of a specific group among the staff at Hospital X and Hospital Y. This is a broader group compared to the other choices, making it more likely to have a higher percentage. Choices A, B, and D are specific to Hospital X or Y only, limiting the pool of individuals being considered and reducing the likelihood of having the highest percentage. Choice C considers the combined staff of two hospitals, increasing the pool of individuals and making it more probable to have a higher percentage of doctors among the staff.

Correct Answer: A

Rationale: To calculate the percent increase, subtract the initial value from the final value (2219 - 1432 = 787). Then, divide the increase by the initial value and multiply by 100 to get the percentage increase [(787/1432) x 100 ≈ 55%]. Therefore, choice A (55%) is correct. Choice B (36%) is incorrect because it underestimates the actual increase. Choice C (64%) and choice D (42%) are also incorrect as they overestimate the percentage increase.

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.
