Answer: 333.75mg
Step-by-step explanation:
Given data:
Dose for 180lb man = 445mg
Dose for 135lb man = ?
let the unknown be x
= 445 / 180 * x / 135
cross multiply both sides
180x = 445 * 135
180x = 60075
Divide both sides by 180
180x / 180 = 60075 / 180
x = 333.75mg
Therefore; a man who weighs 135lbs would require 333.75mg
