The sequence below represents Marisa's fine at the library for each day that she has an overdue book: \( \$ 0.50, \$ 0.65, \$ 0.80, \$ 0.95, \$ 1.10, \ldots \)
Which equation represents Marisa's library fine as a function of a book that is \( n \) days overdue?
\( f(n)=0.15 n \)
\( f(n)=0.50 n \)
\( f(n)=0.15 n+0.35 \)
\( f(n)=0.50 n+0.15 \)
