Question

how long a 30-pound bag of dog food will last. He has 3 big dogs, and each dog eats 2 pounds of food in one day.

Answer 1

Answer:

5 days.

Step-by-step explanation:

We are told that one person has 3 dogs and each dog eats 2 pounds of food in one day.

Let us find amount of food needed for 3 dogs in 1 day by multiplying number of dogs (3) by amount of food eaten by one dog (2 pounds).  

$\text{Amount of food eaten by 3 dogs in one day}=3*2\text{ pounds}$

$\text{Amount of food eaten by 3 dogs in one day}=6\text{ pounds}$

Now let us divide 30 by 6 to find the number of days available food will last.

$\text{30 pound of food bag will last}=\frac{30}{6}$

$\text{30 pound of food bag will last}=5$

Therefore, 30-pound bag of dog food will last for 5 days.
