prompt: A family just bought a newborn puppy that must eat a special type of dog food until it is 1 year old.  The puppy needs to eat 2 ounces of this special dog food per day during the first 60 days of its life.  After that, it needs to eat 4 ounces per day of the special food until it is old enough to eat regular dog food.  If the special dog food is only sold in 5-pound bags, and there are 16 ounces in a pound, how many bags will the family need to buy to feed the puppy until it is old enough to eat regular dog food?

messages.content: The puppy will consume 60*2 = <<60*2=120>>120 ounces of the special dog food in the first 60 days.
  This leaves 365 - 60 = 305 days where the puppy will consume 4 ounces of food per day, or 305*4 = 1220 ounces of the special food.
  Thus, the puppy requires a total of 120 + 1220 = <<120+1220=1340>>1340 ounces of food before it is 1 year old.
  Each 5-pound bag contains 5*16 = <<5*16=80>>80 ounces of special dog food.
  Therefore, the puppy will need to eat 1340/80 = 16.75 bags of the special dog food, meaning the family will need to buy 17 bags.
