Question

Each of Bryan's six dogs eats 2 1/2 cups of dog food every day. If a 20-pound bag of dog food contains approximately 50 cups, how many days can Bryan feed all his dogs with one bag?days

Answer 1

3 days

Explanation:

We must calculate the total amount spent each day, since each dog eats 2 1/2 cups, the six dogs would be:

`6\cdot2(1)/(2)=15\text{ cups of dog food}`

Now, to know how many days are reached, we divide the amount contained in the bag by what is spent each day, like this:

`\begin{gathered} d=(50)/(15)=3.33 \\ d\cong3\text{ days} \end{gathered}`

Which means that he has enough for 3 days to feed his 6 dogs
