Greta bought three 15 pound bags of dry dog food.her dog eats 10 ounces of dry dog food a day. After how many days will gerta need to buy more dog food?
One pound is equal to 16 ounces, so 15 times 16 is 240 ounces. Then 240 divided by 10 ounces is 24. So after the 24 day she'll need to buy more dog food. Hope this helped.
