Question

the adult dosage of a medication is 15mg per day. What is the pediatric dosage of the same medication for a child weighing 52pounds?

Answer 1

EXPLANATION

The average weight of an adult is 136 pounds.

If the adult dosage of a medication is 15mg per day, we can get the pediatric medication by applying the unitary method as shown as follows:

`(15)/(136)=(x)/(52)`

Isolating x:

`52\cdot(15)/(136)=x`

Multiplying numbers:

`(780)/(136)=x`

Simplifying:

`(195)/(34)=x`

Switching sides:

`x=(195)/(34)=5.73`

Answer: the pediatric dosage is 5.73 mg/day.
