A doctor prescribed 18 cubic centimeters of a certain drug to a patient whose body weight was 120 pounds. If the typical dosage is 2 cubic centimeters per 15 pounds of body weight, by what percent should the prescribed dosage be reduced to bring it down to the typical dosage?
(A) 7.5
(B) 9.0
(C) 11.1
(D) 12.5
(E) 14.8
Idea dosage for 120 pound weight = 120 * 2/15 = 16 cc
Dosage recommended earlier = 18 cc
Reduction = 2cc
Kindly note that 2cc need to be removed from 18 cc and not 16 cc Reduction
