Question

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?

f(n) = f(n - 1) • 0.6 + 48, n > 0

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

f(n) = f(n - 1) • 0.4 + 48, n > 0

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

Answer 1

f(n) = f(n-1) * r

Answer 2

what is r in the question

Answer 3

Your rate 40% = .4

Answer 4

f(n)=f(n-1)*0.4 so this means the answer is either B or C right

Answer 5

Why would it be B

Answer 6

oh nvm I didn't see the 250-, it's C

Answer 7
