conversations.value: Can you walk me through the solution of: Drew is reseeding his lawn with grass seed. One bag of grass seed covers 250 square feet of lawn. His lawn is 22 feet from the house to the curb and 36 feet from side to side. He bought four bags of seed. How many extra square feet could the leftover grass seed cover after Drew reseeds his lawn?
conversations.from: assistant
conversations.value: Drew’s lawn is 22 * 36 = 792 square feet.
  He bought enough grass seed to cover 250 * 4 = 1000 square feet.
  Thus, the leftover grass seed can cover 1000 - 792 = 208 square feet.
