An animal shelter is feeding 24 dogs. Each dog is fed 8 ounces of dog food twice a day. How many pounds of dog food does the shelter purchase to feed these dogs for one week?

there are 24 dogs, each one gets 8oz of dog food twice a day, so for 1 day only that'd be 16 oz, for 7 days for 1 dog only that'd be 16+16+16+16+16+16+16 oz or 112oz, just for 1 dog alone for 7 days (week).

now, there are 24 dogs, each one gets 112oz every week, 24 * 112 ounces.
