A developer can buy 250 m2 lots for 300,000 TL in Bostanl and 400,000 TL in Bayrakl. On each Bostanl lot, he can build up to a sx-floor apartment building and on each Bayrakl lot he can build a four-floor apartment building. Since the lot sizes are small, he can have only one 150 sq.m. residence on each floor at both locations. City Hall requires that his developments add 24 apartment floors to the neighborhoods. City Hall also requires that each development earn at least eight civic beautification points. The developer will earn one beautification point for each lot in Bostanl and two points for each lot in Bayrakl. How many lots should the developer buy in each neighborhood to minimize his costs and what is his minimum cost to be paid for land ?
