Astore 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? a. f(n ) = f(n - 1) • 0.4 + 48, n > 0. b. f(n ) = 250 - f(n - 1) • 0.4 + 48, n > 0. c. f(n ) = f(n - 1) • 0.6 + 48, n > 0. d. f(n ) = 250 - f(n - 1) • 0.6 + 48, n > 0.
