B. 340
C. 355
D. 345

Answer

To solve the question \( 85\% \text{ of } (225 + 32.91 \times 5.01) \), we can break it down step by step:

### Step 1: Calculate \( 32.91 \times 5.01 \)
First, we approximate the numbers for easier calculation:
- \( 32.91 \) can be rounded to \( 33 \) (since \( 9 \) is greater than \( 5 \)).
- \( 5.01 \) can be rounded to \( 5 \) (since \( 0 \) is less than \( 5 \)).

Now we calculate:
\[ 33 \times 5 = 165 \]

### Step 2: Add \( 225 \) to the result from Step 1
Now we add \( 165 \) to \( 225 \):
\[ 225 + 165 = 390 \]

### Step 3: Calculate \( 85\% \) of \( 390 \)
To find \( 85\% \) of \( 390 \), we can convert \( 85\% \) to a decimal:
\[ 85\% = \frac{85}{100} = 0.85 \]
Now we calculate:
\[ 0.85 \times 390 \]

To make it easier, we can break it down:
\[ 0.85 \times 390 = \frac{85 \times 390}{100} \]

Calculating \( 85 \times 390 \):
\[ 85 \times 390 = 33150 \]
Now divide by \( 100 \):
\[ \frac{33150}{100} = 331.5 \]

### Step 4: Round the result
Since we are looking for an approximate value, we can round \( 331.5 \) to \( 332 \).

### Final Answer
Thus, the approximate value of \( 85\% \text{ of } (225 + 32.91 \times 5.01) \) is \( 332 \).
