Workings

1. Total cost of building = cost of land + additional cost

                                      =  $115,500 +  $72,336

                                      =  $187,836

2. Total Number of lots available for sales = 8 + 16 +17 = 41

3.   Number of lot sold =  (8-5) + (16 -7) + (17-2)  = 27

4.  cost per Lot  =  $187,836/ 41  =   $4,581.37

5. cost of lot sold =  $4,581.37 * 27 = $123,696.88  

                                                        $123,697
