TEAS Exam Math Practice

Correct Answer: D

Rationale: To determine the order from least to greatest, we need to evaluate each expression. First, calculate each expression: 2^-1 = 1/2 -(4/3) = -4/3 (-1)^3 = -1 (2/5) = 2/5 Now, compare the values: -4/3 is the smallest, followed by -1, then 2/5, and finally 1/2. Therefore, the correct order is -(4/3), (-1)^3, (2/5), 2^-1. Option D correctly lists the expressions in this order. Option A is incorrect because it has the wrong order of the expressions. Option B is incorrect as it has a different order compared to the correct one. Option C is incorrect as it also has a different order than the correct one.

Correct Answer: A

Rationale: To find the sale price after a 20% discount, we first calculate the discount amount: 20% of $30 is $6. Subtracting this discount from the original price gives us the sale price: $30 - $6 = $24, which is choice A. Other choices are incorrect as they do not reflect the correct calculation of the discount. B, C, and D are all higher than the correct answer, indicating incorrect calculations.

Correct Answer: C

Rationale: To find the total potential savings, we first calculate the 20% discount on the car price: 20% of $26,580 = $5,316. Next, we calculate the total monthly payments saved: 3 payments x $250 = $750. Adding the discount and saved payments gives us a total potential savings of $5,316 + $750 = $6,066. Therefore, choice C is correct. Choice A is incorrect because it does not account for the monthly payments saved. Choice B is incorrect as it only considers the discount on the car price, ignoring the saved payments. Choice D is incorrect as it overestimates the savings by combining the discount and payments saved twice.

Correct Answer: D

Rationale: To solve the expression, we follow the order of operations (PEMDAS). First, we evaluate the parentheses: 3 - 4 = -1. Then, we multiply 7 by -1 to get -7. Next, we subtract -7 from 102 to get 109. Finally, subtract 25 from 109 to get the correct answer of 84 (D). Choices A, B, and C are incorrect because they do not follow the correct order of operations or make calculation errors.
