A semiprofessional baseball team near your town plays two home games each month at the local baseball park. They split the concessions 50/50 with the city, but keep revenue from ticket sales for themselves. The city charges the team $100 each month for the 3-month season. The team pays the players and manager a total of $1,000 a month. The team charges $10 for each ticket, and the average customer spends $7 at the concession stand. Attendance averages 30 people at each home game.In order to break even, how many tickets does the team need to sell for each game?

As a waiter you earn $60,000 per year, including tips. Someone offers you a new job as an economic consultant, which pays $100,000 per year. In order to be a consultant, you'll need to rent an office and purchase supplies and new computer equipment. We can conclude which of the following?

In most areas, developers are required to submit environmental impact studies before work can begin on new construction projects. Suppose that a commercial developer wants to build a new shopping center on an environmentally protected piece of property that is home to a rare three-eyed toad. The shopping complex, if approved by the local planning commission, will cover 10 acres. The planning commission wants construction to go forward, since that means additional jobs for the local community, but it also wants to be environmentally responsible. One member of the commission suggests that the developer relocate the toads. She describes the relocation process as follows: "The developer builds the shopping mall and agrees to create 10 acres of artificial toad habitat elsewhere." The builder will agree with the proposed solution under what circumstances?
The benefits of building the shopping center outweigh the costs, including that of relocating the toads.
