55. Determining Revenue The per unit price p (in dollars) of a popular toy when x units (in thousands) are produced is modeled by the function
price =p=12−0.025x
The revenue (in thousands of dollars) is the product of the price per unit and the number of units (in thousands) produced. That is,
revenue =xp=x(12−0.025x)
(a) State the dimensions of a viewing window that shows a graph of the revenue model for producing 0 to 100,000 units.
(b) How many units should be produced if the total revenue is to be 1,000,000$ ?
