Question

Alice has 150 sweaters on the shelves of her store each shelf holds 24 what is the minimum number of shelves she will need for display

Answer 1

Well, you want to take 150 sweaters, and put them into groups of 24 (150÷24) which will get you 6.25, but since you can't have 0.25 of a shelf, you will need 7 for those extra sweaters that go on the 7th shelf.
