D. 16.75

Answer 1

The expression 3[1/2(3.50) + 1.35] is calculated using PEMDAS to first halve 3.50 and then add 1.35, resulting in 3.10. After that, we multiply by 3 to get the final answer, 9.30, which is not one of the provided options.

Step-by-step explanation:

To solve the expression 3[1/2(3.50) + 1.35], we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

First, let's calculate the value inside the parentheses:

Now, we multiply the result by 3:

Therefore, the answer is 9.30, which is not listed as an option in the multiple-choice answers provided (A. 12.00, B. 14.25, C. 10.25, D. 16.75). This could indicate a typo or mistake in the question or answer choices.
