Find a model for the Body Mass Index (BMI) of a person, given that BMI varies directly as a person's weight in pounds and inversely as the square of the person's height in inches. If a 5 ft tall person weighing 95 lb has a BMI of 18.55, how much weight would a 5 ft, 2 in. tall person weighing 127 lb need to gain or lose to have a BMI of 22? Write your answer as a positive value for weight gain or a negative value for weight loss. Round your answer to one decimal place.
