Question
The Venn diagram illustrates the number of people who participated in a survey about their grocery shopping preferences. It consists of two overlapping circles:

1. **Left Circle** - Represents people who go to the grocery store.
   - Contains the number 25, which indicates people who only shop at the grocery store.
   - Contains the variable \( x \), representing those who shop at both the grocery store and the farmer’s market.

2. **Right Circle** - Represents people who go to a farmer’s market.
   - Contains the number 36, indicating people who only shop at the farmer’s market.

3. **Outside the Circles** - The number 8 indicates people who do not shop at either the grocery store or the farmer’s market.

**Question**: According to the Venn diagram, if 60 people were surveyed, how many people shop at both the grocery store and the farmer’s market?

To find \( x \), where \( x \) represents those shopping at both places, we set up the equation based on the total number of surveyed individuals:

\[ 25 + x + 36 + 8 = 60 \]

Simplifying the equation:

\[ 69 + x = 60 \]  
\[ x = 60 - 69 \]  
\[ x = -9 \]

This indicates a miscalculation in assumptions. Adjusting, we should start with:

\[ 25 + x + 36 = 52 \]  
\[ x = 52 - 61 \]  
\[ x = -9 \]

This contradiction highlights that either the initial survey number was misunderstood or values need reshifting without such contradictions.
