Heather’s puppy weighs 23 pounds he has been gaining 3 pounds every month as he grows if this pattern continues how much will the puppy weigh five months from now

If the puppy weighs 3 pounds every month for five months, (5 x 3), that means he will gain 15 pounds in 5 months. Ad when you add that the original weight, (23 + 15), the puppy will weigh 38 pounds  five months from now. 

So the puppy weighs 23 pounds in the beginning. Since he gain three pounds every months, and we are asking for five months, we can use 5×3 since five months and gains three pounds. Then you get 15 pounds, you can answer it as he gained 15 pounds. If you want to continue it, then yku can do 15+23 which you will get 38 as your answer for his weight after five months.
