Question

When Roberto got a puppy from the shelter, it weighed 11 pounds. The puppy gained 40% of its original weight in the first month that Roberto had it. How much did the puppy weigh after the first month ?

Answer 1

11 pounds is your 100%. To get 40 percent of that, multiply 11 times .4, which gets you 4.4. That means the puppy gained 4.4 pounds. 11+4.4= 15.4, so the puppy weighed 15.4 pounds after the first month
