If Susan drinks 10% of the juice from a 16-ounce bottle immediately before lunch and 20% of the remaining amount with lunch, approximately how many ounces of juice are left to drink after lunch?

(A) 4.8
(B) 5.5
(C) 11.2
(D) 11.5
(E) 13.0

Before lunch, she has 0.9 x 16 = 14.4 ounces of juice left. After lunch, she has 0.8 x 14.4 = 11.52 ≈ 11.5 ounces of juice left.

Answer: D
