Michael has a new swimming pool.
To maintain it and keep it clean, he
has to add chlorine to the water. He
adds 28 ounces of chlorine in the
first week. Michael then adds 10
ounces of chlorine every Saturday
morning in the weeks that follow
because 45% of the chlorine in the
pool evaporates each week. Michael
keeps a record of the amount of
chlorine, in ounces, that is in the
pool each week, as shown in the
table,
Week Amount of Chlorine, in ounces

Let f(x) represent the amount of
chlorine in the pool in week x,
where. Which of the following
equations correctly represents f(x)
in terms of for all x > 1?
