An equation for the depreciation of a car is given by y = A(1 – r)t , where y = current value of the car, A = original cost, r =

Mamont248 [21]

<h2>The car is about 6.6 years old.</h2>

Step-by-step explanation:

Given : An equation for the depreciation of a car is given by $y = A(1-r)^t$ , where y = current value of the car, A = original cost, r = rate of depreciation, and t = time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%.

To find : Approximately how old is the car?

Solution :

The value of a car is half what it originally cost i.e. $y=\frac{1}{2} A$

The rate of depreciation is 10% i.e. r=10%=0.1

Substitute in the equation, $y = A(1-r)^t$

$\frac{1}{2} A= A(1-0.1)^t$

$\frac{1}{2}= (0.9)^t$

Taking log both side,

$\log(\frac{1}{2})=t\log (0.9)$

$t=\frac{\log(\frac{1}{2})}{\log (0.9)}$

$t=6.57$

$t\approx 6.6$

Therefore, the car is about 6.6 years old.
