Step-by-step explanation:
Given: Ashley has 100 books that she wants to give away at the rate of n books per week.
Let 'x' denotes the number of weeks .
The number of books Ashley gave after 'x' weeks will be :-
The number of books Ashley has after 'x' weeks will be :-
Hence, the recursive function that gives the number of books Ashley has at any time is , starting at x=1.
