The postal service had a special deal. You could ship up to 2 kg for five dollars for a
limited time. For Amy's friend's birthday, Amy wanted to ship her sweets and candy,
and she wanted to get the best bang for her buck. She first made her cookies. They
had a mass of 400 grams. How many kilogram (s) of sweets and candy could Amy
still ship if only the cookies were in the box for the five dollar special?
