Question

the late fee for library books is $2 Plus $0.15 for each day a book is late . .write a linear equation for the given situation if Maria's is fee for a late book was $3.20 how many days late before the book

Answer 1

8 days

Step-by-step explanation:

Let the late fee by y.

Let the number of days be x.

Therefore, our linear equation can be written as;

`y=0.15x+2`

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

`\begin{gathered} 3.20=0.15x+2 \\ 3.20-2=0.15x+2-2_{} \\ 1.2=0.15x \\ (1.2)/(0.15)=x \\ 8=x \\ \therefore x=8days \end{gathered}`
