128 fluidrams is 16 fluidounces, hence 1 fluidounce is 8 fluidrams.
Cost of 24 fluidrams(3 fluidounces) is
.85*24*.40=8.16
(less discount of 15% is .85) (Option B)
Cost of 24 fluidrams(3 fluidounces) is

16 fluidounces = 128 fluidrams
=> 1 fluidounces = \(\frac{128}{16}\) = 8
=> 3 fluidounces = 3* 8 = 24
Cost of 24 fluidrams = 24 * 0.40 = $ 9.6
Cost after 15% discount = .85 * 9.6 = 8.16
Ans: $8.16
