Question 389262
We have, the price of the truck at the beginning of the first year, P= $10,000
After the first year, it depreciated by 18%. 
So after 1 year, the price P1 = P*(1- (18/100)
After 2 years, the price P2 = P*(1- 2*(18/100)
Similarly at the end of 5th year, price P5 = P*(1- 5*(18/100) = $10,000*(1-0.9)
                                     = $10,000*0.1 = $1000
