Question: Robbie weighs 100 pounds. Patty was 4.5 times as heavy as Robbie, but she has since lost 235 pounds by working out. How many more pounds does Patty weigh than Robbie now?
Stream-of-consciousness: Patty used to weigh 100 * 4.5 = 450 pounds. Patty weighs 450 - 235 = 215 pounds after working out. Patty weighs 215 - 100 = 115 more pounds than Robbie.
