The number of drops of vitamins required for a 20 pound dog each day is 8 drops.
Since a bottle of liquid dog vitamins indicates that a dog gets 2 drops of vitamins each day for every 5 pounds of body weight, we need to find the number of drops per pound of body weight of a dog.
This is gotten by dividing the number of drops by the weight of dog given.
So, number of drops per pound, n = number of drops/weight of dog = 2 drops/5 pounds = 0.4 drops per pound.
Now, we require the number of drops of vitamins a dog should get each day if it weighs 20 pounds.
to get this, we multiply the number of drops per pound by the weight of the dog.
So, number of drops of vitamin = number of drops per pound × weight of dog
So, number of drops of vitamin = 0.4 drops per pound × 20 pounds = 8 drops.
So, the number of drops of vitamins required for a 20 pound dog each day is 8 drops.
