Amusical instrument depreciates by 20% of its
value each year. what is the value, after 2
years, of a piano purchased new for $1200?

$768 is the value of the piano after 2 years.

Step-by-step explanation:

First you need to find 20% of 1,200. To do so you would need to set up a proportion.

=  20 x 1,200 = 24,000/100 = 240

Now, subtract that amount from the original 1,200 to get the amount after one year.

1,200 - 240 = 960.

Next, you need to find 20% of 960 again setting up a proportion.

= 20 x 960 = 19,200/100 = 192

Finally, subtracting this amount from it's new value.

960 - 192 = 768
