a. In trip calculation, it is observed that a Wal-Mart store driver successfully made a total of 104 trips in a given period
of time. During field calculation, it is shown that the calculated number of trips is actually 128. What is the value of the
adjustment factor? ____
b.It is shown that the population of New York City, NY is much greater than that of Irvington, NJ. Employment opportunities,
malls, social activities and tourist sites in New York City are therefore more than that in Irvington. If attractiveness for
New York and Irvington are therefore 1,800 and 180 respectively and if the calculated impedance of migration is known to be
1.57, based on Gravity-Based model, estimate in demands, the number of people who travel between Irvington, NJ and New York
City per week. ____
c.Elasticity can be defined as percentage change in demand for a 1% change in decision attribute. For linear aggregate
demand, what is the mathematical representation/formula for this statement? You must define the parameters you choose to use
for this answer. ____
d.In the City of Joplin, due to weather devastation and hurricane effects, the cost of parking in the local Square has
increased by 20%. This change has not only reduced the number of vehicles that travel to the Square by 5%, but it has also
forced the inhabitants of Joplin to use buses. Bus trips have therefore increased to 20%. With respect to the cost of parking
in the local Square, determine the elasticity of vehicle traffic. ____
e.In the City of Joplin, due to weather devastation and hurricane effects, the cost of parking in the local Square has
increased by 20%. This change has not only reduced the number of vehicles that travel to the Square by 5%, but it has also
forced the inhabitants of Joplin to use buses. Bus trips have therefore increased to 20%. With respect to the cost of parking
in the local Square, determine the elasticity of bus transit. ____
