Alvin is planning to be out of town for the day, so he asks a friend to dog-sit his 3 dogs. Each dog eats 0.5 pounds of food every day. If dog food is sold in 12-ounce cans, how many cans should Alvin leave for the time he is away?

2 cans

Step-by-step explanation:

Calculate how many pounds he needs for one day:

3 (0.5) = 1.5 pounds for each day Alvin is gone (3 represents his dogs,.5 is each dog's food)

Convert into ounces:

1.5*16=24 ounces for one day

Question: If dog food is sold in 12 oz cans, how many will he need?

24/12=2 cans

Thus, he will need 2 cans
