Question

A certain antihistamine is often prescribed for allergies. A typical dose for a 100​-pound person is 22 mg every six hours. Following this​ dosage, how many 12.3 mg chewable tablets would be taken in a​ week?

Answer 1

x = 50 tablets

Explanation:

Ket's call the number of tablets taken in a week "x".

A typical dose for a 100-pound person is 22 mg every six hours, so in 24 hours, they would take 22 mg * 24 hours / 6 hours = 88 mg.

In one week, they would take 88 mg * 7 days = 616 mg.

And since each tablet is 12.3 mg, they would take 616 mg / 12.3 mg/tablet = 50 tablets in a week.

So the answer is x = 50 tablets.
