Provide an appropriate response.
-The rational expression $$\frac { 120 x } { 100 - x }$$ describes the cost, in millions of dollars, to inoculate x percent of the current population of cattle against a particular virus. Choose which of the following statements are true with regard to this mathematical
Model.
I. The expression will be undefined when x = 100.
II. The cost of inoculating 80 percent of cattle is 200 million dollars more than the cost of inoculating 70 percent of
Cattle.
III. This expression will calculate inoculation costs for any population of cattle, no matter what the size.
A) Only I and III are true.
B) All three statements are true.
C) Only I and II are true.
D) Only II and III are true.

The expression is undefined when x = 100 because the denominator becomes zero. The cost difference between inoculating 80% and 70% is indeed 200 million dollars. However, the model does not account for different population sizes, so III is false.
