A210 210-room hotel is filled when the room rate is $ 50 $50 per day. for each $ 1 $1 increase in the rate, three fewer rooms are rented. find the room rate that maximizes daily revenue.

In the short-run, marginal costs are equal to the change in variable costs as output changes. ( mc = change in variable cost / change in quantity) assume that capital is fixed in the short-run. (a) start with the equation for marginal cost and derive an equation that relates marginal cost of production to the cost and productivity of labor. (b) draw a standard looking short-run marginal cost curve and use the equation you derived to explain its shape.
