Question

Challenge: Laura buys a 10 pound bag of dog food. She feeds her dogs 22 ounces of food per day. Will the bag of dog food last a whole week? Explain.​

Answer 1

Yes, the food will last the whole week

Explanation:

10 pounds is 160 ounces. If you multiply 22 by 7 you'll get 154.

Answer 2

Yes, the dog food will last a whole week

Explanation:

1 pound=16 ounces, so

10 pounds=10*16=160 ounces.

There are 7 days in a week, so if Laura feeds her dogs 22 ounces per day, she will need 7*22=154 ounces to last a whole week.

She buys 160 ounces, which is greater than 154, so yes.
