The answer is:
768
As:
1200/5=20%=240
1200-240=960 (after 1 year)
960/5=20%=192
960-192=768 (after 2 years)

Answer:

$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.

[tex]\frac{20}{100}[/tex] = [tex]\frac{x}{1200}[/tex]  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.

[tex]\frac{20}{100}[/tex] = [tex]\frac{x}{960}[/tex] 20 x 960 = 19,200/100 = 192

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

960 - 192 = 768
