The price of a car was $20,000 in 2014, $16,000 in 2015 and $12,800 in 2016. what is the rate of the depreciation of the price of car per year?
a. 15%
b. 20%
c. 25%
d. 30%

b. 20%

Step-by-step explanation:

2014

Car price = 20000

2015

Car price = 16000

Depreciation = 20000 - 16000 = 4000

Depreciation % = (4000/20000)*100 = 20%

2016

Car price = 12800

Depreciation = 16000 -12800 = 3200

Depreciation % = (3200/16000)*100 = 20%
