TEAS 7 Math Practice Test

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.

Correct Answer: C

Rationale: Rationale: To find a reasonable estimate, divide the total distance by the number of days. 1480 miles / 5 days = 296 miles/day. The closest option is 300 miles/day (Choice C). This is the correct answer as it is the most accurate estimate of the daily distance. Choices A, B, and D are incorrect as they are either too low or too high compared to the calculated estimate, making them unreasonable choices.

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: 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: 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.
