TEAS Exam Math Practice

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.

Correct Answer: A

Rationale: To calculate the shop's revenue over three days, we need to consider the total sales of sandwiches, drinks, and cookies over the three days. The revenue formula should include the earnings from each item multiplied by the quantity sold. Therefore, the correct equation is r = 4s + 2d + 1c. This is because for each sandwich sold, the shop earns $4, for each drink $2, and for each cookie $1. Choices B, C, and D are incorrect as they incorrectly multiply the earnings by multiples of the quantities sold, which would result in an inflated revenue amount.

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.
