A carpeted living room and dining room area measures 32 ft by 10 ft. Mark decides to install wood flooring in the 12 ft by 10 ft dining room. By what percent has he reduced the area that is carpeted?

    Ac = (32 ft * 10ft) - (12 ft * 10 ft),
    Ac = 320F^2 - 120 F^2 = 200 F^2 = Area
    carpeted.

    %Re = (200 / 320 - 1)100% = -37.5.
