A new car is purchased for 23900 dollars. The value of the car depreciates at 9.75% per year. To the nearest year, how long will

inna [77]

Answer:

11 years

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$23,900\\r=9.75\%=0.0975\\x=?\\V=\$7,700$

substitute in the formula

$7,700=23,900(1-0.0975)^{x}$

$(77/239)=(0.9025)^{x}$

Apply log both sides

$log(77/239)=xlog(0.9025)$

$x=log(77/239)/log(0.9025)$

$x=11\ years$
