Although Ackerburg's subway system is currently
operating at a deficit, the transit authority will lower
subway fares next year. The authority projects that
the lower fares will result in a ten percent increase
128
in the number of subway riders. Since the additional
income from the larger ridership will more than offset
the decrease due to lower fares, the transit authority
actually expects the fare reduction to reduce or
eliminate the subway system's operating deficit for
next year.
Which of the following, if true, provides the most
support for the transit authority's expectation of
reducing the subway system's operating deficit?
