Question

When Roberto got a puppy from the shelter it weight 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 his first month?

Answer 1

Since 40%=40/100=4/10, we can divide 11 by 10 and multiply that by 4 to get the weight gained, which is 1.1*4=4.4. The weight gained paired with the starting weight = 10+4.4=14.4
