Suppose that, during a certain step in a chemical manufacturing process, the amount of chlorine dissolved in a solution (measured in parts per million (ppm)) is related to the elapsed time measured from the beginning of the step. use the following table as a representation of this relationship.

elapsed time (minutes)
3
6
9
12
15
amount dissolved (ppm)
18.0
20.4
22.4
24.4
26.2

the data is represented in the table graphically with elapsed time (minutes) on the horizontal axis and the amount of dissolved chlorine (ppm) on the vertical axis. what general trend does the data reflect?
a.
there is no apparent trend in the data.
c.
with increasing elapsed time, the amount of dissolved chlorine decreases.
b.
with increasing elapsed time, the amount of dissolved chlorine increases.
d.
with increasing elapsed time, the amount of dissolved chlorine remains the same.
