D. 68.5

Explanation

To solve the equation \( 17\% \text{ of } 250 + ? = 108 \), we can follow these steps:

### Step 1: Calculate 17% of 250
To find 17% of 250, we can use the formula:
\[ \text{Percentage} = \left(\frac{\text{Percentage Value}}{100}\right) \times \text{Total Value} \]
Here, the percentage value is 17, and the total value is 250.

\[ 17\% \text{ of } 250 = \frac{17}{100} \times 250 \]

### Step 2: Simplify the calculation
Now, we can simplify the calculation:
\[ \frac{17 \times 250}{100} = \frac{4250}{100} = 42.5 \]

### Step 3: Substitute back into the equation
Now we substitute this value back into the original equation:
\[ 42.5 + ? = 108 \]

### Step 4: Isolate the question mark
To find the value of the question mark, we can isolate it by subtracting 42.5 from both sides:
\[ ? = 108 - 42.5 \]

### Step 5: Perform the subtraction
Now, we perform the subtraction:
\[ ? = 65.5 \]

### Final Answer
Thus, the value of the question mark is:
\[ ? = 65.5 \]
