Question

A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year.

Answer 1

The given P=15250 
r=7.5/100=0.075 
t=x 
y = 15250*(1 - 0.075)^x 
after 8 years we would have 
x = 8 
y = 15250*(1 - 0.075)^8 
y = $8,173.42 
after 8 years the value of the car would be $8,173.42
