Answer:

Is a proportional relationship

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]

Let

y ----> the total pay

x ---> the number of months

we have

The constant of proportionality is equal to

[tex]k=\$54.99\ per\ month[/tex]

substitute

[tex]y=54.99x[/tex]

therefore

Is a proportional relationship
