Mrs. Brown buys this 5 pound bag of potatoes. There are 18 potatoes in the bag. How many ounces does the bag weigh?

1 pound equals 16 ounces so 5x16=80 ounces

I pound = 16 ounces So it is saying the bag is 5 pounds. So, just think. If one pound is 16, then if you want to know how much ounces 5 pound bag is, you multiply 16 by 5 which is 80. 80 ounces is how much the bag weighs
