El costo mensual en un gimnasio, y, es proporcional al número de veces que el cliente visita al gimnasio,¿cual ecuación representa la relación entre el pago mensual y el número de visitas?

Step-by-step explanation:

The question in English is

The monthly cost in a gym, and, is proportional to the number of times the client visits the gym, what equation represents the relationship between the monthly payment and the number of visits?

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

k represent the constant of proportionality or slope of the linear equation

In this problem

Let

x ----> the number of times the client visits the gym in a month

y ---> the monthly cost in a gym

therefore
