Explanation:
Boston Terriers weigh up to 25 lb.
Suppose a puppy of this breed weighs 15 pounds.
Let the puppy can weigh 'x' pounds more.
So,
![x=25-15=10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gn6fs2cpsa96tia9u9v81xxw4bi50yiw85.png)
But as it is given the maximum weight can be 25 pounds, so the puppy can weigh a maximum of 10 pounds more.
