If average household income increases by 50%, from $40,000 to $60,000 per year, the quantity of rooms demanded at the Lakes from rooms per night to rooms per night. Therefore, the income elasticity of demand is , meaning that hotel rooms at the Lakes are If the price of a room at the Mountaineer were to decrease by 20%, from $200 to $160, while all other demand factors remain at their initial values, the quantity of rooms demanded at the Lakes from rooms per night to rooms per night. Because the cross-price elasticity of demand is , hotel rooms at the Lakes and hotel rooms at the Mountaineer are Lakes is debating decreasing the price of its rooms to $375 per night. Under the initial demand conditions, you can see that this would cause its total revenue to . Decreasing the price will always have this effect on revenue when Lakes is operating on the portion of its demand curve.
