<s>[INST] Your company recently acquired a large piece of land and is planning to build a new office building. The location for the new building has been selected, but the company still needs to figure out the best way to lay out the parking lot. The selected location is surrounded on all sides by dense forest and a 1200 ft long straight road. The parking lot will only be accessed from this road. As part of the planning process, the company has identified several key constraints for the parking lot:
- The length of the parking lot is limited to 800 ft in either direction perpendicular to the road (and an additional 100 ft for administrative space).
- The frontal boundary of the parking lot (parallel to the road) will also need to be set back 40 ft from the edge of the road for both safety and accessibility reasons.
- The company wants to fit as many parking spaces as possible into the lot while still allowing adequate space between lanes and also between individual parking spaces.
- The parking lot will actually be partitioned into two equal sections with a permanent barrier bisecting the space.

Here is what is known about the required amount of space for each parking space:
- The company policy states in parking lots, the minimum space per car is 20 ft in length by 10 ft in width.
- The company also requires that the distance between parking lanes should be 10 ft.
