Options

A. 3832.24
B. 3513 .14
C. 3426.36
D. 3441.64

Answer

To solve the equation \( 4985.23 + ? + 5595.25 = 14022.12 \), we will follow these steps:

### Step 1: Set up the equation
Let \( x \) be the unknown value (the question mark). We can rewrite the equation as:
\[ x + 4985.23 + 5595.25 = 14022.12 \]

### Step 2: Add the known numbers
Now, we will add \( 4985.23 \) and \( 5595.25 \):
\[ 4985.23 + 5595.25 \]
Aligning the numbers:
```
4985.23
+ 5595.25
-----------
```
Adding the decimal parts:
- \( 0.23 + 0.25 = 0.48 \)

Adding the whole numbers:
- \( 4985 + 5595 = 10580 \)

So, the total is:
\[ 10580.48 \]

### Step 3: Substitute back into the equation
Now, we substitute this sum back into the equation:
\[ x + 10580.48 = 14022.12 \]

### Step 4: Solve for \( x \)
To find \( x \), we will subtract \( 10580.48 \) from \( 14022.12 \):
\[ x = 14022.12 - 10580.48 \]

Aligning the numbers for subtraction:
```
14022.12
- 10580.48
-----------
```
Subtracting the decimal parts:
- \( 12 - 48 \): We need to borrow, so it becomes \( 12 + 100 - 48 = 64 \) (we borrowed 1 from the 2, making it 1)
- \( 1 - 0 = 1 \)

Subtracting the whole numbers:
- \( 14000 - 10500 = 3500 \)
- \( 3500 + 1000 = 4600 \)

So, the total is:
\[ x = 3431.64 \]

### Final Answer
Thus, the value of the question mark \( ? \) is:
\[ \boxed{3431.64} \]
