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? (1 point)

f(n) = f(n - 1) 0.4 + 48, n 0

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

f(n) = f(n - 1) 0.6 + 48, n 0

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

f(n) = f(n - 1) 0.4 + 48, n > 0
		
f(n) = 250 - f(n - 1) 0.4 + 48, n > 0
		
f(n) = f(n - 1) 0.6 + 48, n > 0
		
f(n) = 250 - f(n - 1) 0.6 + 48, n > 0

I believe (almost sure) it's one of the first two. I'm guessing the B, but I'm not 100%
