Question

How much is the fine if Taylor checked out a book from the library and it is now 5 days late and the late fee is 10 cents per day?

Answer 1

Late `f` be the fine
Late `d` be the number of days late

There is no flag-down late fee, so the equation for the fine is

`f = 10d`

Since the book is 5 days late

`f = 10*5`

`f = 50`
