Meredith lives in apartment building in Boston. There is an elevator that starts at ground level and runs to the roof of the building. The elevator travels 12 3/4 feet between each level. Meredith takes the elevator from the ground level to the 7th level, then continues to the roof. How many levels will the elevator still have to travel to reach the roof if the building is 191.25 feet tall? Show your work. (3 points)
