Jbought three 15pund bags of dry dog food. her dog eats 10 ounces of dry dog food a day. after how many days will j need to buy more dog food?and explain how to

You know that: 15 pounds = 240 ounces

1st day- 10 ounces

2nd day- 20 ounces

3rd day- 30 ounces

And so on

I can easily tell in 24 days J's dog will finish one bag.

10 ounces x 24 days = 240 ounces of dry dog food

Now I know that in 24 days J's dog finishes one bag of dry dog food, I also know that there are three bag of dry dog food and it takes 24 days to finish one 15 pound bag. So I will multiply 24 days by 3 bags of dog food.

24 days x 3 bags of dog food = 72 days

ANSWER: IT WILL TAKE 72 DAYS TO FINISH 3 BAGS OF 15 POUND DOG FOOD.
