16. The demand for airline travel is quite sensitive to price.
Typically, there is an inverse relationship between
demand and price; when price decreases, demand in-
Chicago and Los Angeles is $600, the demand (D)
is 500 passengers per day. When the price is reduced

c. By trial and error, can you find the optimal solu-
tion that maximizes total revenue?
Use the data given in the three scenarios below to
produce scatter plots, determine the type of model
demonstrated in each example and then answer the
questions based on the graph you created.
Scenario 1 Rescue 911
In a rural community, fire and paramedic crews
must service a large region. They often cover 2
or 3 towns several kilometres apart. These
crews travel, on average, 70 km/h to their
destination. The Chief of Station 42 wants to determine
the time required to reach the patient's home (response
time) for his region. The station is located next to the
local hospital. The Chief knows the distances to each
community that he services, including Deerborn, the
furthest community, at 55 km away. Using the data
below, create a scatter plot showing the relationship
between distance to patient and response time.

Suppose a team of researchers is studying how compression hosiery, typical shoes, and medical shoes affect range of ankle motion. In particular, note the variables Barefoot and Footwear1.
