Question

A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments. Which recursive function best represents the number of bottles in the store, given that f(0) = 50?

Answer 1

f(n) = f(n-1)*.6 + 20

Explanation:

f(0) = 50

f(n) = f(n-1)*.6 + 20

In fact, since f(0) = 50, f(n) = 50.
