Convert The Function
XYZ, inc. produces widgets at a cost of $12 a widget. After analyzing the demand for their widgets at various price levels, they have come up with the following function to model the demand at each price level:
\(D(x) = -200x+7000\)
How can XYZ, Inc. convert the function \(D(x)\) into the function \(E(x)\) that will model the cost-of-goods sold at each price level?
