Question 158542: a financial advisor has conducted some research and has advised a company that the cost of producing their new transistor radio c, can be modeled by the equation c=18.96x+5275, where x is the number of radios produced. The advisor has also conducted research to determine that the best selling price of the radio is $29.99. As a result, the best model for the company's revenue R is the equation R=29.99x, where x is the number of radios sold.
The company executives have decided that they are willing to invest $10,000 in the new product. If this money is to be used for the costs of the radios, how many radios should the company be able to produce?
If the company produces the maximum number of radios with their $10,000 investment and all the radios are sold, how much revenue will the company generate from the new product?
