Ed tried to evaluate the expression [tex][7+3 \times(9-4)] \div 2[/tex]. Here is his work:

[tex]
\begin{aligned}
& [7+3 \times(9-4)] \div 2 \\
= & [10 \times(9-4)] \div 2 \\
= & [10 \times 5] \div 2 \\
= & 50 \div 2 \\
= & 25
\end{aligned}
[/tex]

Is Ed's work correct?

A. No, Ed made a mistake in Step 1. Ed should have done the operation inside the parentheses first. The order of operations says to start with parentheses and do brackets next.

B. No, Ed made a mistake in Step 2. Ed should have multiplied instead of subtracting. The order of operations says to multiply before you subtract.

C. Yes, Ed's work is correct.

Answer :

Let's evaluate whether Ed's work is correct. We need to follow the correct order of operations, which is Parentheses, Exponents (which we don't have here), Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

Let's go through each step of the expression [tex]\([7+3 \times (9-4)] \div 2\)[/tex].

### Step-by-Step Solution:

1. Perform the operation inside the parentheses:
[tex]\[
9 - 4 = 5
\][/tex]

2. Multiply the result by 3:
[tex]\[
3 \times 5 = 15
\][/tex]

3. Add 7 to the result from the multiplication:
[tex]\[
7 + 15 = 22
\][/tex]

4. Divide by 2:
[tex]\[
22 \div 2 = 11
\][/tex]

### Conclusion:
Ed's work resulted in a final answer of 25. However, when we followed the correct order of operations, the result should be 11. Therefore, Ed made a mistake. Specifically, his calculations went awry after correctly evaluating the multiplication but before completing the addition and division.
