When the two substances are mixed, we see an increase in the temperature,

The flat horizontal line at the beginning of the graph tells us the initial temperature of mixing the two substance.

The initial temperature of mixing is ≈22.5 oC

and, final temperature would be the next flat horizontal line ≈32.5 oC from the given graph
