A new car is purchased for 15500 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car be,
mixer [17]

Answer:

\$9,709.17  

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=\$15,500\\r=7.5\%=0.075\\x=6\ years

substitute

V=\$15,500(1-0.075)^{6}=\$9,709.17
