Answer 1

Sure! We can fill in the missing values based on the information provided in the table. Given the table's structure, we can set up the equations as follows:

1. **Youths who prefer printed books**: Let it be \( x \).
2. **Youths who prefer electronic books**: Given as \( 70 \).

From the total for youths, we know:
\[
x + 70 = \text{Total for Youths}
\]

3. **Adults who prefer printed books**: Given as \( 23 \).
4. **Adults who prefer electronic books**: Let it be \( y \).

From the data provided, we know the total number of adults:
\[
23 + y = \text{Total for Adults}
\]

5. The total for printed books is given as \( 58 \), so:
\[
x + 23 = 58
\]
From this, we can solve for \( x \):
\[
x = 58 - 23 = 35
\]
So, the number of youths who prefer printed books is \( 35 \).

6. The overall electronic book total is \( 130 \):
\[
70 + y = 130
\]
Solving for \( y \):
\[
y = 130 - 70 = 60
\]
So, the number of adults who prefer electronic books is \( 60 \).

Now we can summarize the filled values:

- **Youths**:
- Print: \( 35 \)
- Electronic: \( 70 \)
- Total: \( 35 + 70 = 105 \)

- **Adults**:
- Print: \( 23 \)
- Electronic: \( 60 \)
- Total: \( 23 + 60 = 83 \)

Lastly, let's confirm the overall totals:
- Total Print: \( 35 + 23 = 58 \) (correct)
- Total Electronic: \( 70 + 60 = 130 \) (correct)
- Grand Total: \( 105 + 83 = 188 \)

So the completed table is:

| Age Group | Print | Electronic | Total |
|-----------|-------|------------|-------|
| Youths | 35 | 70 | 105 |
| Adults | 23 | 60 | 83 |
| Total | 58 | 130 | 188 |
