Answer: Please refer to the explanation section
Step-by-step explanation:
When income raises demand raises this tells us the Triple Sevens hotel rooms are a normal good.
Hotels rooms at the Exhilaration are a direct substitute for Triple sevens' Hotel Rooms'. When the price of hotel room per night at The exhilaration decrease by 20%, the demand for Triple Sevens hotel room falls from 150 to 50 rooms. this tells us that the price elasticity of demand is negative, if Triple sevens raises it price the quantity of rooms per night demanded will fall.
The Demand for Triple Sevens hotel rooms is elastic, the demand for hotel rooms is sensitive to price changes. When the price of triple sevens' hotel rooms decrease, the quantity of hotel rooms demanded will increase which will then increase revenue of Triple Seven. Decreasing the Price will always increase the revenue as long as the Demand is elastic with a negative price elasticity of demand.
Initial demand conditions
- Demand must be elastic
- Price Elasticity must be Negative
- The Good being sold is a normal good (Positive income elasticity)
