- What is the explanation of the solution and answer to the problem: Boxes of floor tiles are to be offered for sale at a special price of $75. The boxes claim to contain at least 100 tiles each. b. How may the seller benefit if the numbers 12,16,7,8,21,4,11,6,5 and 10 are used to draw the stem-and-leaf diagram instead of the actual numbers of tiles? Answer: Seller may notice that 10+16+7+8+21+4+11+6+5+10=100,which means that 11 (rather than ten) boxes of 100 tiles could be offered for sale.arrow_forwardWhat is the explanation of the solution and answer to the problem: Boxes of floor tiles are to be offered for sale at a special price of $75.
