Options

A. a. 13
B. b. 8
C. c. 3
D. d. 4

Answer

To solve the equation \( 2508 + 15.02 + ? \times 11 = 200 \), we will follow these steps:

### Step 1: Rearrange the equation
We start by moving the unknown term (question mark) to the other side of the equation. This gives us:
\[ 2508 + 15.02 + ? \times 11 = 200 \]
Subtract \( 2508 \) and \( 15.02 \) from both sides:
\[ ? \times 11 = 200 - 2508 - 15.02 \]

### Step 2: Calculate the right side
Now, we need to calculate the right side:
\[ 200 - 2508 - 15.02 = 200 - 2523.02 = -2323.02 \]
So, we have:
\[ ? \times 11 = -2323.02 \]

### Step 3: Isolate the question mark
Next, we divide both sides by 11 to isolate the question mark:
\[ ? = \frac{-2323.02}{11} \]

### Step 4: Perform the division
Now, we perform the division:
\[ ? = -211.18 \]

### Final Answer
Thus, the value of the question mark is approximately:
\[ ? \approx -211.18 \]
