Respuesta :

Answer:

8 days

Explanation:

Let the late fee by y.

Let the number of days be x.

Therefore, our linear equation can be written as;

[tex]y=0.15x+2[/tex]

So if the late fee, y = $3.20, let's go ahead and find the number of days, x;

[tex]\begin{gathered} 3.20=0.15x+2 \\ 3.20-2=0.15x+2-2_{} \\ 1.2=0.15x \\ \frac{1.2}{0.15}=x \\ 8=x \\ \therefore x=8days \end{gathered}[/tex]
