Answer:
To find out how much it would cost Suzie to lay the flooring so it fully covers the floor of room, you need to know the area of the room's floor and the cost per square foot of the flooring.
If the flooring will cost $2 per square foot, and if the area of the room's floor is x square feet. Then the total cost will be $2x.
