A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments. Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250?

A. f(n) = f(n - 1) • 0.6 + 48, n 0

B. f(n) = 250 - f(n - 1) • 0.4 + 48, n 0

Wasn't C

D. f(n) = 250 - f(n - 1) • 0.6 + 48, n 0

Well, it is unlikely to have the value "250" in there, anywhere.  That rather narrows it down.
