Part 1
Suppose a business purchases equipment for ​$12 comma 00012,000 and depreciates it over 5 years with the​ straight-line method until it reaches its salvage value of ​$20002000 ​(see the figure​ below). Assuming that the depreciation can be for any part of a​ year, answer the questions to the right
​(a) Write an equation that represents the depreciated value V as a function of the years t.
Vequals=12000 minus 2000 t12000−2000t
​(Do not​ factor.)
Part 2
​(b) Write an inequality using t as the variable that indicates that the depreciated value V of the equipment is less than ​$60006000.
12000 minus 2000 t less than 600012000−2000t<6000
​(Do not​ simplify.)
Part 3
​(c) Write an inequality that describes the time t during which the depreciated value is at least half of the original value.
