D. 43

Answer

To solve the expression \(80\% \text{ of } 50\% \text{ of } 250\% \text{ of } 34\), we can break it down step by step.

### Step 1: Convert Percentages to Decimal
First, we need to convert the percentages into decimal form:
- \(80\% = \frac{80}{100} = 0.8\)
- \(50\% = \frac{50}{100} = 0.5\)
- \(250\% = \frac{250}{100} = 2.5\)

### Step 2: Calculate 250% of 34
Now, we calculate \(250\%\) of \(34\):
\[ 250\% \text{ of } 34 = 2.5 \times 34 = 85 \]

### Step 3: Calculate 50% of the Result from Step 2
Next, we calculate \(50\%\) of the result from Step 2:
\[ 50\% \text{ of } 85 = 0.5 \times 85 = 42.5 \]

### Step 4: Calculate 80% of the Result from Step 3
Finally, we calculate \(80\%\) of the result from Step 3:
\[ 80\% \text{ of } 42.5 = 0.8 \times 42.5 = 34 \]

### Final Answer
Thus, the final answer is:
\[ 80\% \text{ of } 50\% \text{ of } 250\% \text{ of } 34 = 34 \]
