Substitute n = 10-3 into the given function:
f(10-3) = 1.5 + 0.5(10-3 - 1) = 1.5 + 0.5(9) = 1.5 + 4.5 = 6
Therefore, the overdue fine for a library book defined by the function f(10-3) is $6.00. Answer: None of the given options match.
The function f(n) = 1.5 + 0.5(n −1)
models a book fine, in dollars, that a library charges for a book that is n days overdue.
What is overdue for a library book defined by the function f(10−3)?
