The dosage of a cold medication is 2 mg for every 60 lb of body weight. How many milligrams of this medication are required for a person who weighs 135 lb?
To calculate how many milligrams of medication are required for a person who weighs 135 lb, we first need to determine the amount of medication needed for every 60 lb of body weight.
2 mg is recommended for every 60 lb of body weight.
135 lb is 2.25 times the amount of 60 lb (135 / 60 = 2.25).
Therefore, for a person who weighs 135 lb, the amount of medication needed would be:
2 mg x 2.25 = 4.5 mg
So, 4.5 milligrams of medication are required for a person who weighs 135 lb.
