Why is $L'=\{u\#v^R ~|~ u,v \in L\}$ and $L\in RL$ a regular language?
Regular languages are closed under reversal, therefore $L^R = \{v^R \mid v \in L\}$ is regular. Moreover, regular languages are closed under concatenation, therefore $L' = L \circ \{\#\} \circ L^R$ is ...

Your question's answer could be solved by Finite Automata with output that is Moore Machine or Mealy Machine.
You have three cases:
$Case:1$ When temperature is equal or more than $80°$ then output is ...
