To create the revenue function, R(x), we'll first need to come up with an equation to estimate the
demand for the \Bad Dog" hot dog, based on selling price. Consider what we know. Salty Dogz
would sell 200 hot dogs when the price for the \Bad Dog" is $2 but they would only sell 150 hot
dogs when the price is $4 per hot dog. Letting x represent the selling price of the hot dog, write
the equation of the line containing the points: (2, 200) and (4, 150).
