conversations.value: This math problem has got me stumped: A 1000 car parking lot is divided into 3 sections. There are 320 spaces in section 1, and 200 more in section 2 than in section 3. How many spaces are made available in section 2 of the parking lot?
  Can you show me the way?

conversations.value: There are a total of 1000 spaces - 320 spaces = 680 spaces in both sections 2 and 3.
  Let the number of spaces in section 3 be x. The number of spaces in section 2 = x + 200.
  We know that 320 + x + 200 + x = 1000.
  Combining like terms, we get 2x = 480
  Dividing both sides by 2 produces x = 240.
  The number of spaces in section 2 is 240 + 200 = 440.
