The following graph input tool shows the daily demand for hotel rooms at the Triple Sevens Hotel and Casino in Las Vegas, Nevada. To help the hotel management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool.

The following graph input tool shows the daily demand for hotel rooms at the Triple Sevens Hotel and Casino in Las Vegas, Nevada. To help the hotel
management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand
factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool.
Demand Factor
Initial Value
Average American household income
$50,000 per year
Roundtrip airfare from Los Angeles (LAX) to Las Vegas (LAS)
$100 per roundtrip
Room rate at the Exhilaration Hotel and Casino, which is near the Triple Sevens
$250 per night
Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph.
Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.

For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Triple Sevens is charging $200 per
room per night.
If average household income increases by 20%, from $50,000 to s60,000 per year, the quantity of rooms demanded at the Triple Sevens
v from
rooms per night to
rooms per night. Therefore, the income elasticity of demand is
, meaning that hotel rooms at the
Triple Sevens are
Ir the price of an airline ticket from LAX to LAS were to increase by 10%, from $100 to $110 roundtrip, while all other demand factors remain at their
initial values, the quantity of rooms demanded at the Triple Sevens v from
rooms per night to
rooms per night. Because the
cross-price elasticity of demand is
, hotel rooms at the Triple Sevens and airline trips between LAX and LAS are
Triple Sevens is debating decreasing the price of its rooms to $175 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 Triple Sevens is operating on the
v portion of its demand curve.
