Depreciation Suppose a business purchases equipment for $12,000 and depreciates it over 5 years with the straight-line method until it reaches its salvage value of $2000 (see the figure below). Assuming that the depreciation can be for any part of a year, do the following:

a. Write an equation that represents the depreciated value V as a function of the years t.

---

b. Write an inequality that indicates that the depreciated value V of the equipment is less than $8000.

---

c. Write an inequality that describes the time t during which the depreciated value is at least half of the original value.
