Answer:
20%
Explanation:
Calculation for the total appreciation in house price
Since we are looking for total appreciation in house price Let new house price be P
P=200,000*80%
P=80,000
P=200,000*80%+80,000
P=240,000
Hence,
Total appreciation=240,000/200,000-1=
Total appreciation=20%
Therefore the total appreciation in house price will be 20%
