Ashley has 100 books that she wants to give away at the rate of n books per week. write a recursive function that represents the number of books ashley has at any time. the recursive function that gives the number of books ashley has at any time is

We have to write a recursive formula that represents the number of books Ashley has at any time. At start Ashley has 100 books. If y is the number of books she has at any time, n is the number of books she wants to give away each week and x is the number of the weeks: y = 100 - n x . For example: n = 5. After 10 weeks: x = 10 and y = 100 - 5 * 10 = 100 - 50 = 50 books.  y = 100 - n x.
