You can put this solution on YOUR website! A musical instrument depreciates by 20% of its value each year. What is the value, after 2 years, of a piano purchased new for $1200?
-------------
After 1 yr, it's $1200 - (20/100)*1200
= $1200*0.8 = $960
---------
After 2 yrs, it's $960 - (20/100)*960
= $960*0.8 = $768
============================
Or,
= $1200*0.8^2
= $768
