D. 36

Answer

To solve the equation \( ?\% \text{ of } 924 + 39 = 371.64 \), we can follow these steps:

### Step 1: Set up the equation
Let \( x \) be the percentage we are trying to find. We can express the equation as:
\[ \frac{x}{100} \times 924 + 39 = 371.64 \]

### Step 2: Isolate the percentage term
To isolate the term involving \( x \), we first subtract 39 from both sides of the equation:
\[ \frac{x}{100} \times 924 = 371.64 - 39 \]
Calculating the right side:
\[ 371.64 - 39 = 332.64 \]
So, we have:
\[ \frac{x}{100} \times 924 = 332.64 \]

### Step 3: Solve for \( x \)
Next, we can multiply both sides of the equation by 100 to eliminate the fraction:
\[ x \times 924 = 332.64 \times 100 \]
Calculating the right side:
\[ 332.64 \times 100 = 33264 \]
Thus, we have:
\[ x \times 924 = 33264 \]

### Step 4: Divide to find \( x \)
Now, we divide both sides by 924 to solve for \( x \):
\[ x = \frac{33264}{924} \]
Calculating this gives:
\[ x = 36 \]

### Conclusion
Thus, the value of \( ? \) is \( 36 \). Therefore, \( 36\% \) of \( 924 + 39 = 371.64 \).
