Ответ:
The smallest possible number of years for the depreciation value of car is 7 years .
Step-by-step explanation:
Given as :
The purchased price of car = $26000
The depreciation rate of car every year = r = 30%
The reduced price of car after n years = $2200 or less
Let The time period for the depreciation value = n years
Now, According to question
The reduced price of car after n years = The purchased price of car ×![(1-\dfrac{\textrm rate}{100})^{\textrm time}](/tpl/images/0409/3805/bd5fe.png)
Or, $2200 = $26000 ×![(1-\dfrac{\textrm r}{100})^{\textrm n}](/tpl/images/0409/3805/0d928.png)
Or,
= ![(1-\dfrac{\textrm 30}{100})^{\textrm n}](/tpl/images/0409/3805/4a2a7.png)
Or, 0.084615 =![(0.7)^{n}](/tpl/images/0409/3805/463d6.png)
Now, Taking Log both side
So,
0.084615 =
(
)
Or, -1.07255 = n
0.7
Or, -1.07255 = n ( - 0.15490 )
∴ n =![\dfrac{1.07255}{0.15490}](/tpl/images/0409/3805/351de.png)
I.e n = 6.92 ≈ 7 years
So, Time period for depreciation of car value = n = 7 years
Hence The smallest possible number of years for the depreciation value of car is 7 years . Answer
