Answer:
Therefore the final elevation of the butterfly is 4 m.
Step-by-step explanation:
i) initial elevation = 20 m
ii) change in elevation = -16m
iii) therefore final elevation = initial elevation + change in elevation 
                =   20 m + (-16 m)  
               =   (20 - 16) m
                =    4 m 
Therefore the final elevation of the butterfly is 4 m.
