Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
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. Final answer: 440.
