Answer:  The function of Rae's earnings : [tex]f(x)=60+5.25x[/tex]

She would make $81 after 4 hours.

Step-by-step explanation:

Let x be the number of hours Rae works.

Given : Rae earns $60 for playing music on Saturday nights at the local coffee house. She makes an average of $5.25 in tips per hour.

Then , the function of Rae's earnings will be :_

[tex]f(x)=60+5.25x[/tex]

Now, for x = 4 hours , we get

[tex]f(4)=60+5.25(4)=81[/tex]

Hence, she would make $81 after 4 hours.
