Mary ordered a bike online. She received her bike in three separate boxes. In the first box were the frame and handlebars, they weighed 5 pounds. In the second box, she found the tires and seat. The second box weighed 2 pounds. In the last box, Mary found the brakes and wheels. The last box weighed 7 pounds. What will the bike weigh after it is put together?
7+5+2= 14 pounds. The sum of the parts is ALWAYS equal to the whole.
