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)

singhabhijeet · Answer

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

Ans: Option B

128/x = 16/3
128 x 3 = 16x
x = 24

24 x 2/5 = 48/5

17/20 x 48/5
816/100 = 8.16
Which is answer B

Chemerical71 · Answer

Given that, 1 fluideounces = 8 fludgrams
 3 equals 24 ( 8*3)
 24*.4 = 9.6

as it is given that 15% discount allowable on Medicare patients 
thus, 9.6 * .15= 8.16 (B).

KarishmaB · Answer

Charge =  \frac{85}{100}  of  \frac{$0.40}{fluidram}  * 3 fluidounces =  \frac{17}{20} * \frac{$0.4}{fluidram} * 3 * \frac{128}{16}  fluidrams

Charge = $8.16

Answer (B)

JeffTargetTestPrep · Answer

We are given that a particular medicine costs $0.40/1 fluid dram. A particular Medicare patient needs 3 fluid ounces. Let’s first convert 3 fluid ounces to fluid drams.

Since 128 fluid drams = 16 fluid ounces, 8 fluid drams = 1 fluid ounce.

Thus, 3 fluid ounces = 3 x 8 = 24 fluid drams.

Thus, the regular cost for 24 fluid drams is 24 x 0.4 = $9.60; however, with a 15% discount, the cost is 9.6 x 0.85 = $8.16.

Answer: B

laddaboy · Answer

There are 24 fluidrams, which cost 9.60$ without discount, with discount they would be <9.60$ , closet and the realistic answer choice is B.

generis · Answer

Discount for Medicare patients per fluidram: 
$0.40 * .85 = $0.34
fluidram = Fl.ram
fluidounce = Fl.ounce

Setting up factors so that most units cancel. In conversion problems, the method is usually very efficient. Set the factors up so that the units you want remain (here, dollars):

\frac{$0.34}{(1)Fl.ram}*\frac{128Fl.rams}{16Fl.ounces}* 3Fl.ounces= $8.16

Answer B
