    Answer: Mrs. Jefferson should plan to spend 119.1 on wallpaper

    Step-by-step explanation:

    She would like to wallpaper everything but the door. It means that the area to be covered by the wallpaper would be the area of the 4 walls of the room - the area of the door.

    The room is 18ft in length and 12ft in width. Thea area of each side of the room is

    18 * 12 = 216 square feet

    Area of the 4 sides of the room is

    216 * 4 = 864 square feet

    The door is 7ft in width and 3 ft in length. Area of door is

    7 * 3 = 21 square feet

    Area to be covered is

    864 - 21 = 843 square feet

    Each roll of wallpaper covers approximately 160 square ft. Therefore, the number of rolls needed is

    843/160 = 5.26

    Since the rolls cannot be a fraction, then she needs 6 rolls

    Since a roll costs 19.85, the cost of 6 rolls is

    19.85 * 6 = 119.1
