If the patient needs 450 milligrams and each cubic centimeter contains 50 milligrams, we proceed to make a rule of three like this
1cc contains 50mg
x. contains 450mg
1*450=450
450/50=9 =x
The result is 9 cubic centimeters, the closest answer among the options is 10 cc with each meal, so if you require 3 doses, multiply by 3 obtaining 30 cc per day.
