To determine how much Colin charges for one tutoring session, we can set up a simple equation based on the information provided.

**Given:**
- Total number of tutoring sessions = 21
- Total earnings = \$1,575
- Cost per session = $$ s $$ dollars

**Step 1: Set Up the Equation**

The total earnings can be expressed as:
$$ \text{Number of Sessions} \times \text{Cost per Session} = \text{Total Earnings} $$
$$ 21 \times s = 1575 $$

**Step 2: Solve for $$ s $$**

To find the cost per session ($$ s $$), divide both sides of the equation by 21:
$$ s = \frac{1575}{21} $$

**Step 3: Calculate the Value**

$$ s = 75 $$

**Conclusion:**
Colin charges **\$75** for each tutoring session.
Colin charges \$75 for each tutoring session.
