if a school has a hot-dog special for lunch. there are 18 classrooms and there are 28 students in each class. estimate to the nearest ten to find out about how many hot dogs does the school need to order?

Wouldn't it be 20 x 30?

This looks like a very rough estimate. How big are the students? I like your estimate, Bobpursley.
