DETAILED EXPLANATION

Look at 0.78%2Ahighlight_red%28+x+%29%2B1.
Replaced x with 2.83
It becomes 0.78%2Ahighlight_green%28+2.83+%29%2B1.
Look at highlight_red%28+0.78%2A2.83+%29%2Bhighlight_red%28+1+%29.
Replace constants in expression: highlight_red%28+0.78%2A2.83+%29,highlight_red%28+1+%29 with highlight_green%28+3.2074+%29
It becomes highlight_green%28+3.2074+%29.
Result: 3.2074
