Nik has 200 crayons. He wants to separate them into groups of 8 and put them into boxes.  Each box weighs 8 ounces. Each crayon weighs 1 ounce. If he puts all of his crayons into boxes, what is the total weight, in pounds, of the crayons and the boxes, when there are 16 ounces to a pound?
First find how many boxes Nik needs. 200 crayons / 8 crayons per box = <<200/8=25>>25 boxes.
25 boxes * 8 ounces per box = <<25*8=200>>200 ounces.
Each crayon weighs 1 ounce, so 200 + 200 = <<200+200=400>>400 ounces.
400 ounces / 16 ounces per pound = <<400/16=25>>25 pounds.
