Question

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, ...

Which equation represents Marisa’s library fine as a function of a book that is n days overdue?

Answer 1

The correct answer for the question that is being presented above is this one: "C. f(n) = 0.15n + 0.35." The equation that represents Marisa’s library fine as a function of a book that is n days overdue is f(n) = 0.15n + 0.35

Here are the following choices:
A. f(n) = 0.15n
B. f(n) = 0.50n
C. f(n) = 0.15n + 0.35
D. f(n) = 0.50n + 0.15

Answer 2

f(n) = 0.15n + 0.35

Explanation:

The given sequence is 0.50, 0.65, 0.80, 0.95, 1.10...

The difference between successive terms is 0.15

f(n) =0.15(n) + 0.35

Answer: f(n) = 0.15n + 0.35

Hope this will helpful.

Thank you.
