conversations.value: I need a clearer understanding of how to solve: Darnell has 1000 square feet of fabric that he's using to make mini flags. He makes square flags that are 4 feet by 4 feet, wide rectangular flags that are 5 feet by 3 feet, and tall rectangular flags that are 3 feet by 5 feet. He has already made 16 square flags, 20 wide flags, and 10 tall flags. How many square feet of fabric does he have left?
conversations.from: assistant
conversations.value: The square flags use 16 square feet of fabric per flag because four times four equals 16
  The wide flags each use 15 feet of fabric per flag because five times three equals 15
  The tall flags each use 15 feet of fabric per flag because five times three equals 15
  He has used 256 square feet for the square flags because 16 times 16 equals 256
  He has used 300 square feet for the wide flags because 20 times 15 equals 300
  He has used 150 square feet for the tall flags because ten times 15 equals 150.
  He has used 706 square feet because 256 plus 300 plus 150 equals 706.
  He has 294 square feet left because 1,000 minus 706 equals 294
