if jack's truck is worth $4000 now but losing 8% of its value every year, what will it be worth in 5 years

you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. use this information to write a linear aquation that gives the dollar value V of the product in terms of the year. (let t=12 represent 2012). 2012 value $156 and rate 4.50 increase per year.
