Problem Overview

In a mental health hospital, there is one doctor and numerous patients. Each day, every patient engages in a behavior where they bite someone, which may also lead to self-inflicted injuries.

Daily Biting Behavior

Over the course of seven days, each patient bites twice. Meanwhile, the doctor experiences a total of 100 bites during this period.

Mathematical Representation

Let x represent the number of patients in the clinic. The total number of bites over seven days can be formulated as follows:

  • Total bites from patients: 7x
  • Total bites experienced by the doctor: 2x + 100

Solving the Equation

By setting the total bites equal to each other, we have the equation:

7x = 2x + 100

Solving for x gives us:

Conclusion

After simplifying the equation, we find that x = 20. Therefore, there are 20 patients in the clinic.
