If 12 cans of food can feed 8 dogs for one week,
how many cans of food would be needed to feed
6 dogs for two weeks?

possible answers
9
12
16
18

Answer 1

I believe that the answer is 18.

If 12 cans of food can feed 8 dogs for one week, 1.5 cans of food can feed 1 dog for one week.

Now, there are 6 dogs in need of food for 2 weeks. 6 times 1.5 = 9. 9 times 2 (weeks) is 18. Therefore, 18 cans of food would be needed to feed 6 dogs for 2 weeks
