B. 160.3
C. 153.1
D. 162.5

Answer

To solve the equation \( 14\% \text{ of } 905 + ? = 287 \), we can follow these steps:

### Step 1: Calculate 14% of 905
To find 14% of 905, we can use the formula:
\[ \text{Percentage} = \frac{\text{Percentage Rate}}{100} \times \text{Total} \]
So, we calculate:
\[ 14\% \text{ of } 905 = \frac{14}{100} \times 905 \]
Calculating this gives:
\[ = 0.14 \times 905 = 126.7 \]

### Step 2: Set up the equation
Now we can rewrite the original equation using the value we just calculated:
\[ 126.7 + ? = 287 \]

### Step 3: Isolate the variable ?
To find the value of ?, we need to isolate it on one side of the equation. We can do this by subtracting 126.7 from both sides:
\[ ? = 287 - 126.7 \]

### Step 4: Perform the subtraction
Now we perform the subtraction:
\[ 287 - 126.7 = 160.3 \]

### Final Answer
Thus, the value of ? is:
\[ ? = 160.3 \]
