1. **State the problem:** Amy charges 65 per student for a 6-week session and collects a total of 1690 from one group. We need to find the number of students in that group. 2. **Formula:** Total amount collected = (Number of students) \times (Price per student) 3. **Set up the equation:** $$65 \times x = 1690$$ where $x$ is the number of students. 4. **Solve for $x$:** $$x = \frac{1690}{65}$$ 5. **Simplify the fraction:** $$x = \frac{\cancel{1690}}{\cancel{65}} = 26$$ 6. **Answer:** There are **26 students** in the group.
