Explanation

To solve the equation \( 68\% \text{ of } 1288 + 26\% \text{ of } 734 - 215 \), we will follow these steps:

### Step 1: Calculate \( 68\% \text{ of } 1288 \)
To find \( 68\% \text{ of } 1288 \), we can use the formula:
\[ 68\% \text{ of } 1288 = \frac{68}{100} \times 1288 \]
Calculating this gives:
\[ 68 \times 1288 = 87584 \]
Now divide by 100:
\[ \frac{87584}{100} = 875.84 \]

### Step 2: Calculate \( 26\% \text{ of } 734 \)
Next, we calculate \( 26\% \text{ of } 734 \):
\[ 26\% \text{ of } 734 = \frac{26}{100} \times 734 \]
Calculating this gives:
\[ 26 \times 734 = 19084 \]
Now divide by 100:
\[ \frac{19084}{100} = 190.84 \]

### Step 3: Add the results from Step 1 and Step 2
Now we add the results from the two calculations:
\[ 875.84 + 190.84 = 1066.68 \]

### Step 4: Subtract 215 from the sum
Next, we subtract 215 from the sum:
\[ 1066.68 - 215 = 851.68 \]

### Step 5: Round off the result
Since we are looking for an approximate value, we round off \( 851.68 \) to the nearest ten:
\[ 851.68 \approx 850 \]

### Final Answer
Thus, the final answer is approximately \( 850 \).
