Javier is $175 \%$ heavier than his brother. If Javier's brother weighs 80 pounds, how much does Javier weigh?

Step 2 ：Find the actual weight difference between them: \(1.75 \times 80 = 140\)

Step 3 ：Add this weight difference to his brother's weight to find Javier's weight: \(80 + 140\)

Step 4 ：\(\boxed{220}\)
