Optimizing FAR

1) P = -F

= Price for all housing and location factors besides FAR

F = FAR

= marginal impact of FAR on Price per square foot.

2). C = + F

= "baseline" cost of "stick" SFU construction

= marginal impact of FAR on cost per square foot

Given:

Profit Function:

Profit Function = P*F - C

Profit Function = F - F2 - ( + F)

Profit Function = F - F2 - - F

Question:

Take the Derivative of the profit function with respect to F (p/F = 0)?
