TEAS 7 Math Practice Test

Correct Answer: A

Rationale: The correct answer is A: $90. Given the ratio of 1:3 for house savings to rent, and the rent of $270 per month, we can set up a proportion. Let x be the amount saved for the house. The ratio equation is: x/270 = 1/3. Cross-multiplying gives x = 270/3 = $90. Therefore, the roommate saves $90 each month. Choice B: $270 is incorrect because that is the amount of rent paid, not the amount saved for the house. Choice C: $730 is incorrect as it is not derived from the given ratio and rent amount. Choice D: $810 is incorrect as it is also not in line with the ratio and rent information provided.

Correct Answer: B

Rationale: Correct Answer: B ($48,443) Rationale: To find the total price of Veronica's new car, add the base price ($40,210) to the cost of the surround sound system ($3,015) and the maintenance package ($5,218). Therefore, $40,210 + $3,015 + $5,218 = $48,443. Summary of other choices: A: $50,210 - Incorrect as it only includes the base price of the car. C: $43,225 - Incorrect as it only includes the base price and the maintenance package. D: $40,210 - Incorrect as it only includes the base price of the car.

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: The correct answer is B because it accurately describes the rate of change as the snow melting by 5 centimeters every day. This statement represents a consistent decrease in the snow level over time. Choice A is incorrect as it implies a higher rate of melting than what is described. Choice C is incorrect as it describes an increase rather than a decrease. Choice D is also incorrect as it describes an increase instead of the intended decrease in snow level. Therefore, choice B is the most accurate representation of the rate of change in this scenario.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.
