r= 0.40 $/1 fdram
=> r = .40 $/(16/128) founce
hence for 3
tot amt = 0.40 * 128 * 3 / 16
= 9.60 $
85% of tot amt = 8.16
IMO B ???

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.sanju09 wrote:A hospital pharmacy charges $0.40 per fluidram of a certain medicine but allows a discount of 15 percent to Medicare patients.

(A) $9.60

(C) $3.20
(D) $2.72
(E) $2.24
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
