City Condos Construction, CCC, obtained a loan to purchase city land for a premium condominium building. CCC paid a real estate analyst $100,000 to write a report on the market. The report stated that each condo will sell for $5 million and they will build 10 condos on each building floor. The city's condo market is competitive but limits condo towers to 6 floors only. Construction costs rise with the number of floors built. The construction costs are $5 million (or $5m) to build one floor, $20m for two floors, $45m for 3 floors, $80m for four floors, $125m for five floors, and $180m for six floors. (Notice these values are not per floor costs.) In addition to these costs, CCC pays $1m per year in interest on its loan which it cannot avoid and will pay overhead costs for construction of $5m per year which are incurred only when construction occurs. Use the following graph as an approximate guide to solving the following questions. Costs and revenues are in $millions.
