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. a. v = 12,400 minus 820 t; $6660 b. v = 12,400 minus 820 t; $5840 c. t = 12,400 minus 820 v; $6660 d. t = 12,400 minus 820 v; $7480
