16 fluidounces = 128 fluidrams
=> 1 fluidounce = 128/16 fluidrams = 8 fluidrams.

The discount is 15%. Hence medicare patients are charged = 85% = 0.85

Hence, Cost to medicare patient = (3*8fluidrams)*0.85*(0.40$) = 3*8*17/20*2/5 = $(51*16)/100 = $8.16

B is correct. :)

128 fluidrams = 16 fluidounces => 3 fluidounces = (128*3)/16 = 24 fluidrams

Total cost to patient = (24 fluidrams)($0.40/fluidram) * (0.85)= $8.16

Choose B
