Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

<u>PEMDAS</u>

<u>Parentheses</u>
<u>Exponents</u>
<u>Multiply</u>
<u>Divide</u>
<u>Add</u>
<u>Subtract</u>

<u>BODMAS</u>

<u>Brackets</u>
<u>Order</u>
<u>Divide</u>
<u>Add</u>
<u>Subtract</u>

<u>First, do parentheses.</u>

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

<u>Do multiply and divide.</u>

6*9=54

54/3=18

<u>Then, rewrite the problem down.</u>

$\Longrightarrow: \sf{3+18-7}$

<u>Add.</u>

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

<u>Therefore, the correct answer is "C. 14".</u>

I hope this helps, let me know if you have any questions.
