Answer:
Step-by-step explanation:
%decrease is given by = decrease/actual value ×100
Then in this case
The value decrease from 180,000 to 165,000
Then, the decrease is 180,000-165000=15,000
The actual value was 180,000
Then %decrease = decrease/ actual value × 100
%decrease= 15,000/180,000×100
%decrease=8.33%
Decrease = 8.33%
