Hello!

To control an infection, a doctor recommends that a patient who weighs 92 pounds be given 320 milligrams of antibiotic. If the antibiotic is given proportionally according to the patient's weight, how much antibiotic should be given to a patient who weighs 138 pounds ?

Weighs ........ milligrams  

92 -------------- 320

138 ------------- X

multiply the means by the extremes 

92*x = 320*138

92x = 44160

x = 44160/92

x = 480  

Answer:  

480 milligrams
