Question 4 of 13 • Algebra I

The sequence below shows Marisa’s library fine starting on the first day her book is overdue and for each additional day afterward:$0.50, $0.65, $0.80, $0.95, $1.10, ...Let f(n) represent Marisa’s library fine (in dollars), where n is the number of days the book has been overdue, starting with n=1 for the first day overdue.Which equation represents Marisa’s library fine as a function of a book that is n days overdue?

Answer

f(n) = 0.15n

f(n) = 0.50n

f(n) = 0.15n + 0.35

f(n) = 0.50n + 0.15
