sam needs to feed 10 dogs at the animal
shelter. The dog food is sold in 5 pounds. Each dog eats 2 pounds of dog food each day. How many bags of dog food will he need to feed the dogs for the entire week? estimate your answer.(first estimate then multiply) 
What do you estimate the answer to be?
Now let's figure it out.
10 dogs at 2 pounds a day = ?
7 days times the total number of pounds the 10 dogs eat = ?
Finally, divide the number of pounds the 10 dogs eat in a week by 5 pounds to find the number of bags needed.
