1. The amount Lin's sister makes at her part-time job is $9.60 an hour.
a. Write an equation in the form of [tex]y=kx[/tex] where [tex]x[/tex] represents the hours she works and [tex]y[/tex] represents the amount of dollars she earns.
b. Is [tex]y[/tex] a function of [tex]x[/tex]? explain how you know.
c. write an equation describing [tex]x[/tex] as a function of [tex]y[/tex]
I already have solved A and B, where the answer to A is y=9.6x, and B is yes because in the equation, y is dependent on x. The only trouble I have is making an equation where x is dependent on y. Can someone help?
