N ps = N m * N o / (1 + N m * S o/S p) (1)

where N m is the number of operators that a
physiotherapist supervises, N o is the number of patients that
an operator coaches in one hour, S p is a physiotherapist’s
salary, and S o is an operator’s salary.

We assume that a physiotherapist and an operator coach
a patient for 90 and 45 minutes, respectively. Therefore:

N o = 2 * N p (2)

N p is the number of patients that a physiotherapist
coaches in one hour. The ratio between N ps and N p is as
