Lizzy: The building has 42 storage units that are a total of 5040 square feet. Twenty of the units are 8 by 4 feet each. If the remaining units are all the same size, what is the area, in square feet, for one of the remaining units?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
8 * 4 = 32 square feet. 20 * 32 = 640 square feet. 5040 - 640 = 4400 square feet. There are 42 - 20 = 22 remaining units. 4400 / 22 = 200 square feet. One of the remaining units is 200 square feet. Final answer: 200.
