Question

True
False​

Answer 1

Answer:

False, the depreciation rate is not 9.4%.

Step-by-step explanation:

Given:

Cost of 7-year old car =  $10,500.

Cost of new car = $21,000

depreciation rate =  9.4%.

Solution:

Initial price minus the price after 7 years gives us the depreciation price  

Therefore,

=21000-10500

=10500

Hence the price reduced by 10,500 in 7 years.

Therefore, the depreciation per year is  

=$\frac{10,500}{7}$

=1,500

Hence, the depreciation rate percentage can be found out as follows:

Depreciation rate% = $\frac{1500}{21000}\times 100$=7.14%

Hence, the answer is false.
