If the recommended weight w, in pounds, for a male is given in terms of his height h, in inches, by the formula w = 4.5h – 154, how much greater is eric's recommended weight than tom's, according to this formula?

18

Tom's height be

and

Eric's height will be 4 inches more

let's plug these two information into the formula given in the question

for the difference in their weight;

Eric's weight will be;

w =

Tom's weight will be

w =

taking the difference between the two expressions above

w =

opening the bracket

w =

w = 18 pounds

so Eric's weight is 18 pounds more than Tom's
