The total fixed cost (including engineering and designing the machine "platform," re-tooling a production line, creating a series of commercials and print ads, etc.) for manufacturing a new model range of TVs is $ 25 million. If the manufacturer's selling price for the flagship (largest screen size, more bells, and whistles) is going to be $ 600, and the variable cost of making this TV is $ 450, how many TVs does the manufacturer have to sell in order to make a $ 5 million profit? Please type your answer, including the intermediary calculations using the space below.
