1. **Problem Statement:** Charlie makes 8 dollars for each hour of work. We need to write an equation to represent his total pay $p$ after working $h$ hours. 2. **Understanding Proportional Relationships:** When one quantity is proportional to another, the total amount is the product of the rate and the quantity. Here, the rate is 8 dollars per hour. 3. **Writing the Equation:** The total pay $p$ is the rate (8) multiplied by the number of hours worked $h$. $$p = 8h$$ 4. **Explanation:** This means if Charlie works 1 hour, he earns $8 \times 1 = 8$ dollars; if he works 5 hours, he earns $8 \times 5 = 40$ dollars, and so on. This equation models the total pay based on hours worked.
