whats the total print

Answer 1

To fill in the missing values, let's analyze the given information systematically.

### Given Information:
- Total number of youths = 70 - total (which gives us the total of adults and youths combined)
- Total number of adults who prefer electronic = 23 - electronic
- Total electronic preference for all = 58 - electronic
- Overall total number of individuals = 130 - total

### Summarizing Known Values
1. **Total** = 130
2. **Youths** = 70 - Youths (so, total Youths = Total - Adults)
3. **Adults** = Total - Youths
4. **Adults, Electronic** = 23

Let’s break it down step by step:

1. **Total of Youths and Adults:**
\[
\text{Youths + Adults} = 130
\]

2. **Total Electronic Preferences:**
\[
\text{Youths, Electronic} + \text{Adults, Electronic} = 58 \quad \text{(Total Electronic)}
\]
Given that Adults, Electronic = 23:
\[
\text{Youths, Electronic} + 23 = 58 \implies \text{Youths, Electronic} = 58 - 23 = 35
\]

3. **Now, we know:**
- Youths, Electronic = 35
- Adults, Electronic = 23

4. **Now we can find the total number of youths:**
\[
\text{Youths} = 70 \quad (needs to be calculated)
\]
Since total for Youths and Adults = 130:
\[
\text{Youths} + \text{Adults} = 130 \implies \text{Adults} = 130 - 70 = 60
\]

5. **Total Print Preferences:**
From the data, both for Youths and Adults:
- Total for Adults = 60, and since Adults, Electronic = 23, then:
\[
\text{Adults, Print} = 60 - 23 = 37
\]

6. **For Youths:**
- Total Youths = 70, with Youths, Electronic = 35 then:
\[
\text{Youths, Print} = 70 - 35 = 35
\]

### Final Calculation for Print Preferences
**Final Values:**
1. Youths, Print = 35
2. Adults, Print = 37

**Total Print Preferences:**
\[
\text{Total Print} = \text{Youths, Print} + \text{Adults, Print} = 35 + 37 = 72
\]

### Conclusion
The total number of people who prefer reading books printed on paper is **72**.
