If someone's estimate is far different from the others, work with them to figure out why. Write an equation that shows how to find the minimum number of boxes needed for a room m, where A is the area of the room and s is the number of square feet per box. Write an equation that shows how to find the cost for each room r, where n is the number of boxes ordered and C is the cost per box. Professionals typically order 10% more than calculated. If w represents the minimum number of whole boxes needed, what expression represents the number of boxes they would order?
