The value of almost everything you own (assets), such as a car, computer, or house, depreciates (goes down) over time. when an asset�s value decreases by a fixed amount each year, the depreciation is called straight-line depreciation. suppose your truck has an initial value of $12,400 and depreciates $820 per year.

number of years 1 2 3 4 5
value of the truck 11,580 10,760 9,940 9,120 8,300

write an equation that illustrates this function if you plan to keep the truck for 7 years and determine the value of the truck at the end of this period. let v represent the dependent variable and let t represent the independent variable.
