A certain medication recommends that each day a person be given 8 mg for every 100 lbs of weight. If 10,000 people take this medication each day and their average weight is 180 lbs, how many kilograms of this drug are used daily?

Total Mass of daily drug used = 144 Kg

Explanation:

Total weight of the individuals =

180lbs * 10000 = 1.8 * 10^6 lbs

Since the drug is to be given 8 mg for every 100 lbs;

number of 8 mg doses = 1.8 * 10^6 / 100 = 1.8 * 10^4 doses

Total mass of the doses = 1.8 * 10^4 * 8 mg = 1.44 * 10^5 mg.

We divide the value above by 1000 to convert to Kg.

Therefore, total daily mass of drug used = (1.44 * 10^5)/1000 = 144 Kg
