A store had 175 cell phones in the month of January. Every month, 10% of the cell phones were sold and 10 new cell phones were s

tocked in the store.
Which recursive function best represents the number of cell phones in the store f(n) after n months?
(A) f(n) = 175 - 0.9 * f(n - 1) + 10, f(0) = 175, n > 0
(B) f(n) = 0.1 * f(n - 1) + 10, f(0) = 175, n > 0
(C) f(n) = 175 + 0.9 * f(n - 1) + 10, f(0) = 175, n > 0
(D) f(n) = 0.9 * f(n - 1) + 10, f(0) = 175, n > 0
