At birth, a puppy weighed 5.5 ounces. When it was adopted 9 weeks later, its weight was 3.5 times its birth weight. What was the puppy’s weight when it was adopted?

Multiply the puppy’s birth weight by 3.5: 5.5 × 3.5 = 19.25 ounces. The puppy weighed 19.25 ounces when adopted, so the correct choice is B) 19.25 ounces.
